Hazelcast unique ScheduledExecutorService on replicated map gets lost on node shutdown

I'm trying to run a Hazelcast ReplicatedMap spread over multiple nodes for caching. The map will have about 60.000 entries and the loading/creation of entries is really expensive.
The entries of the map occasionally become invalid, need to be updated or removed or new entries have to be inserted in the map. For this I thought about a scheduled service that updates the map on a regular basis.
To prevent concurrency and costly duplicate creation of new entries there should be only one reload service.
To test this I made a little test case:
public class HazelTest {
private ReplicatedMap<Long, Bean> hzMap;
private HazelcastInstance instance;
public HazelTest() {
instance = Hazelcast.newHazelcastInstance();
hzMap = instance.getReplicatedMap("UniqueName");
IScheduledExecutorService scheduler = instance.getScheduledExecutorService("ExecutorService");
try {
scheduler.scheduleAtFixedRate(new BeanReloader(), 5, 10, TimeUnit.SECONDS);
} catch (DuplicateTaskException ex) {
System.out.println("reloader already running");
}
}
public static void main(String[] args) throws Exception {
Random random = new Random(System.currentTimeMillis());
HazelTest test = new HazelTest();
System.out.println("Start ...");
long i = 0;
try {
while (true) {
i++;
Bean bean = test.hzMap.get((long) random.nextInt(1000));
if (bean != null) {
if (i % 100000 == 0) {
System.out.println("Bean: " + bean.toString());
}
bean.setName("NewName");
}
}
} finally {
test.close();
System.out.println("End.");
}
}
public void close() {
instance.getPartitionService().forceLocalMemberToBeSafe(5, TimeUnit.SECONDS);
if (instance.getPartitionService().isLocalMemberSafe()) {
instance.shutdown();
} else {
System.out.println("Error!!!!!");
}
}
}
The reloader:
public class BeanReloader implements NamedTask, Runnable, HazelcastInstanceAware, Serializable {
private transient HazelcastInstance hazelcastInstance;
#Override
public void run() {
System.out.println("Bean Reload ....");
for (long i = 0; i < 200; i++) {
Bean bean = new Bean(i, "Bean " + i);
ReplicatedMap<Object, Object> map = hazelcastInstance.getReplicatedMap("UniqueName");
map.put(i, bean);
}
System.out.println("Reload end.");
}
#Override
public void setHazelcastInstance(HazelcastInstance hazelcastInstance) {
this.hazelcastInstance = hazelcastInstance;
}
#Override
public String getName() {
return "BeanReloader";
}
}
The bean has only 2 fields for test purpose:
public class Bean implements Serializable {
private long id;
private String name;
// getter and setter
}
Now when I run this in different terminals on my machine (or over network, does make no difference) the nodes show the desired behaviour: the service is only running on one node at a time - when I start another one I get a DuplicateTaskException.
But when the node currently executing the task goes down the service is not always switched to another node. There is about 2/3 chance that the service is completely lost and not running on any of the remaining nodes.
Now my questions: is this behaviour normal? Do I have to check for running service myself, and if so via what api?
Or am I getting something wrong and there is another way to achieve my goals? Is hazelcast replicated map the right aproach in the first place?
Edit: edited the code as the simplifications I made for posting did not show the error any more.
There are no errors in the log when a node leaves and the service is not restored. The only logging is on one node:

Did a testrun with debug logs on 4 nodes (hz1-4.log). Node 4 picked up the schedule. After one run I killed that node (log timestamp 15:28:50,955 in hz4.log). Here are the four logs from that run (note: due to the vast amount of logging I only pasted the logs from timestamp 15:28:50,955 on ...)
hz3.log
hz2.log
hz1.log
hz4.log
With that setup I can reliably reproduce the failure. I just start the 4 nodes with
mvn exec:java -Dexec.mainClass="de.tle.products.HazelTest" -Dnumber=X
where X is the number of the node (just a variable in the log4j conf file). After all four nodes a running kill the one currently running the schedule and then the schedule is not running on any of the remaining nodes.

Esper rules for different users

I recently started programming with Esper and I have a smart wearable that sends pedometer data to my laptop. I then process this data using esper. But suppose I have multiple smart wearables with each an unique MAC address. I use time windows and my question is how can I change my rule file so that the rules only fire for events with the same macaddress and take appropiate action based on this MAC address. My initialization and rule are:
Configuration cepConfig = new Configuration();
cepConfig.addEventType("Steps", Steps.class.getName());
// We setup the engine
EPServiceProvider cep = EPServiceProviderManager.getProvider("myCEPEngine", cepConfig);
EPRuntime cepRT = cep.getEPRuntime();
// We register an EPL statement
EPAdministrator cepSteps1 = cep.getEPAdministrator();
EPStatement cepStatementSteps1 = cepSteps1.createEPL("select * from "
+ "Steps().win:time(1 hour) "
+ "group by macAddress "
+ "having sum(max(steps)-min(steps)) < 100");
cepStatementSteps1.addListener(new rule1Listener());
My Steps class has the following fields:
double steps;
String stepsTimestamp;
String macAddress;
And this is how I insert the events:
Steps steps0 = new Steps(0, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps0);
Steps steps00 = new Steps(0, new Date(timeStamp).toString(), "LD24ESF74");
cepRT.sendEvent(steps00);
Steps steps1 = new Steps(25, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps1);
Steps steps2 = new Steps(50, new Date(timeStamp).toString(), "LD24ESF74");
cepRT.sendEvent(steps2);
Steps steps3 = new Steps(55, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps3);
Steps steps4 = new Steps(105, new Date(timeStamp).toString(), "LD24ESF74");
cepRT.sendEvent(steps4);
Steps steps5 = new Steps(75, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps5);
Steps steps6 = new Steps(110, new Date(timeStamp).toString(), "K5E45H778");
cepRT.sendEvent(steps6);
This is my output:
Sending tick: Steps: 0.0 Timestamp: Mon Mar 14 18:13:23 CET 2016 Mac Address: K5E45H778
->Rule 1 fired: K5E45H778
Sending tick: Steps: 0.0 Timestamp: Mon Mar 14 18:18:23 CET 2016 Mac Address: LD24ESF7474
->Rule 1 fired: LD24ESF7474
Sending tick: Steps: 25.0 Timestamp: Mon Mar 14 18:23:23 CET 2016 Mac Address: K5E45H778
->Rule 1 fired: K5E45H778
Sending tick: Steps: 105.0 Timestamp: Mon Mar 14 18:28:23 CET 2016 Mac Address: LD24ESF7474
Sending tick: Steps: 55.0 Timestamp: Mon Mar 14 18:33:23 CET 2016 Mac Address: K5E45H778
->Rule 1 fired: K5E45H778
Sending tick: Steps: 75.0 Timestamp: Mon Mar 14 18:38:23 CET 2016 Mac Address: K5E45H778
Sending tick: Steps: 110.0 Timestamp: Mon Mar 14 18:43:23 CET 2016 Mac Address: K5E45H778
Why doesn't the rule fire for the one but last event of 75 steps?

The SQL-standard "group by" clause is for aggregation per group. Thus just adding "group by macAddress" should get it done.

Web service method called once, but executed multiple times

I'm developing a web service in Java EE 6, with only one method called E1CreateAccount.
It happens that for each call I do to the method, the execution of the method fires multiple times (at least 2 times). The executions are consecutive, so the next start when the previous ends.
The code of the method is the following:
#WebMethod
public Object E1CreateAccount(#WebParam(name = "arg0") InboundAccountF56101IB newAccount) {
Object ret = "KO";
MyAction action = MyAction.CREATE;
MyLogger.getLogger().info("Integration WebService called to Create new Account in E1, name " +
newAccount.getCRMAccountName());
E1AccountClientThread runner = new E1AccountClientThread();
runner.initialize(newAccount, action);
Thread thread = new Thread(runner);
MyLogger.getLogger().info(thread.getId() + ": Created thread to " + action.name() +
" Account. Account Name: " + newAccount.getCRMAccountName() + "...");
try {
MyLogger.getLogger().info(thread.getId() +
": Starting thread to call E1 Account web service, Action: " +
action.name());
thread.start();
ret = "OK";
} catch(Exception e) {
String str = "Exception calling the thread delegate to call E1 Account web service (Action " +
action.name() + ". Message: " + e.getMessage().toString();
MyLogger.getLogger().severe(str);
ret="KO " + str;
}
return ret;
}
It receive the call, it logs the fact that the service has been called, and then create a separated thread which will do the task. Then it always return the string "OK".
The method works well, the only problem is the multiple execution, which is undesired for the software purposes.
This is what I see from the logs:
Jul 06, 2015 3:17:57 PM integration.services.e1.account.E1AccountService E1CreateAccount
INFO: Integration WebService called to Create new Account in E1, name THIS_IS_THE_COMPANY_NAME

(I substituted with [...] the logs related to what the threads actually do because I think it is not relevant)
The web service has been deployed on WebLogic 12.1.3, and I used the ide JDeveloper 12.1.3

Selenium - Address already in use: connect

I am trying to crawl and parse a dynamic content of website using selenium,
Generally the website am crawling loads its content by the scroll event from the page,So i triggered the scroll event by selenium until the end of the page is reached.
In Product phase am fetching each product detail by loop iteration, it also works fine.. but when it reaches iteration count of 280 above....
This is my code below...
private void init() throws IOException {
FirefoxProfile profile = new FirefoxProfile();//Create Firefox profile
profile.setPreference("javascript.enabled", true);//Allow javascript for browser
WebDriver htmDriver = new FirefoxDriver(profile);//add profile to firefoxDriver
htmDriver.get(urlTextField.getText());//Get and Connect to the url from URL text Field
htmDriver.manage().window().maximize();//Maximize the Browser window
String count = htmDriver.findElement(By.cssSelector("#numbFound > #no-of-results-filter")).getText();//Total Product Count for the category
//System.out.println("Total Category Count : "+count);
htmDriver.findElement(By.cssSelector(".list")).click();//Click to view the Product in List
htmDriver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);//Wait
int lCount = Integer.parseInt(count);//Calculate the scroll length
for (int i = 1; i <= Math.ceil(lCount / 5); i++) {
//Generate Arrow Down Action
htmDriver.findElement(By.id("products-main4")).sendKeys(
Keys.ARROW_DOWN);
htmDriver.findElement(By.id("products-main4")).sendKeys(
Keys.ARROW_DOWN);
htmDriver.findElement(By.id("products-main4")).sendKeys(
Keys.ARROW_DOWN);
htmDriver.findElement(By.id("products-main4")).sendKeys(
((JavascriptExecutor) htmDriver).executeScript(
"window.scrollBy(0,document.body.scrollHeight)", "");
htmDriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
}
//Product Phase
int row2 = 0;
List<WebElement> rdata = htmDriver.findElements(By.className("product_list_view_cont"));//selector to select each product row
for (WebElement data : rdata) {
String title = data.findElement(By.cssSelector(".product_list_view_heading")).getText();//Get Product Title
System.out.println(title);
//Check if Product Price available
boolean product_price = data.findElements(By.cssSelector(".product_list_view_price_outer span")).isEmpty();
if(product_price == false){
//Get the Price of the Product
String price = data.findElement(By.cssSelector(".product_list_view_price_outer var[id^=selling-price-id-]")).getText().trim();
System.out.println(price);
}else{
//If Price not Available add make the data null
system.out.println("No price")
}
String brand = data.findElement(By.cssSelector("ul.key-features li")).getText();
System.out.println(brand);
String brandUrl = data.findElement(By.cssSelector(".product_list_view_info_cont a")).getAttribute("href");//Fetch Brand Url
System.out.println(brandUrl);
String status = data.findElement(By.cssSelector(".product_list_view_buy-outer .lfloat")).getText();//Fetch Brand Url
System.out.println(status);
}
}
