I am running Titan 0.5.0 with Cassandra 2.0.8.
When I first ran my Java client with a local Titan-Cassandra I could connect to it. Now that I deployed the Titan-Cassandra remotely on a Debian Wheezy with dedicated user I have a "Connection refused exception" (see stack below). I can connect to Titan via Rexter on the remote server via http://my-domain.com:8182 and I can see my vertices and edges.
What is the changes to do on a local configuration (Java client and Titan on same machine) to make Titan with Cassandra and Elasticsearch run on a remote machine accessed by my Java client?
Java client code
private final URL titanConfiguration =TitanRepository.class.getResource("/conf/titan-cassandra.properties");
public TitanGraph load() {
return TitanFactory.open(titanConfiguration.getPath());
}
Working configuration with local Titan-Cassandra:
Java configuration titan-cassandra.properties
storage.backend=cassandrathrift
storage.hostname=127.0.0.1
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5
index.search.backend=elasticsearch
index.search.hostname=127.0.0.1
index.search.client-only=true
schema.default=none
No change in the Titan conf directory
NOT working java configuration with Titan-Cassandra on remote server
Java configuration titan-cassandra.properties
storage.backend=cassandrathrift
storage.hostname=192.168.1.20 <<< OR http://my-domain.com
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5
index.search.backend=elasticsearch
index.search.hostname=192.168.1.20 <<< OR http://my-domain.com
index.search.client-only=true
schema.default=none
changes in Titan conf directory
rexster-cassandra-es.xml:
<base-uri>http://my-domain.com</base-uri>
<index.search.hostname>192.168.1.20</index.search.hostname>

If Rexster runs on the same (remote) box and can connect, but you can't connect from your local machine, then it's most likely a Cassandra configuration issue. In cassandra.yaml set rpc_address to 0.0.0.0 (currently you've probably set it to 127.0.0.1), restart Cassandra and try to connect again.

as far as I can tell, the issue seems to stem from the agent not being able to retrieve the appId, but sshing into the container and performing a curl
curl https://westeurope-3.in.applicationinsights.azure.com/api/profiles/<INSTRUMENTATION_KEY>/appId
does return a result, leading me to believe that the pod does have a connection to the Azure monitor instance.
I've tried multiple versions of the agent jar, tried the SDK and custom events inside the spring-boot app, manually starting a secondary java instance, provided the connection string/instrumentation-key using kubectl, local env variable, applicationinsights.json file, and as a JVM parameter, all this to no avail.
right now it feels like I'm all out of ideas and unable to get any further with this issue without some external input.
Does anyone recognize this issue, or tackled something similar before?
I've faced similar situation and it seems that in my case, the Java app was running inside a VM without outbound access to the internet. This way,it wasn't reaching Azure Monitor/App Insight DNS and not sending the data to the ingestion service.
Have you tried running a CURL within your app infrastructure and making sure it can outbound http traffic?
I am having a trouble with launching Intellij Idea Ultimate Edition 2021.1.2 (also tried 2020.3.1) with VPN enabled (I am using GlobalProtect) on Windows 10. I've been working on this setup for quite a long time, but recently something went wrong with no obvious changes made. So, after launching Intellij Idea I get an error window with following:

Your JRE: 11.0.11+9-b1341.57 amd64 (JetBrains s.r.o.)
C:\Program Files\JetBrains\IntelliJ IDEA 2021.1.2\jbr
After I prees OK button IDE shuts down. If I disable VPN everything works fine.
After some research I found the way to start Idea with VPN enabled with VM option -Djava.net.preferIPv4Stack=true, but that really doesn't solve the problem, because I still need VPN for my project.
If I start Idea and then enable VPN, after I try to start project I get Cannot assign requested address: no further information message from Gradle. Or if I simply open Maven project, I get

Any ideas on how to resolve this issue?
Adding system variable _JAVA_OPTIONS:-Djava.net.preferIPv4Stack=true resolved all issues
I have IntelliJ and other development tools stopped working today.
IntelliJ says on start:
Cannot start internal HTTP server. Git integration, JavaScript
debugger and LiveEdit may operate with errors. Please check your
firewall settings and restart IntelliJ IDEA
Before this happened I was receiving strange errors on loopback connection on build which is now gone. Currently it says
Error:failed to create a child event loop
Gradle build says:
Protocol family unavaliable
Disabling firewall does not help.
UPDATE
IntelliJ log is full of messages like this:

UPDATE 2
I found the root of the problem: this was caused by proxy autoconfiguration. By some reason address of 127.0.0.1 was processing by proxy and was leading to the web page of proxy server. The addition of
function FindProxyForURL(url,host)
{
if( host == '127.0.0.1' ) {
return "DIRECT";
}
to wpad.dat helped but I still don't understand an entire effect. I have proxy for a long time and it was no causing such an effect previously.
So I think this is also somehow related with IPv6 or something.
I'm trying to submit a job (a simple word count) to hadoop-2.5.0 (installed on a ubuntu 14.04.1 server running on a virtual machine) from eclipse on windows. In the job configuration, i've set "fs.defaultFS" to "hdfs://192.168.2.216:8020" (as suggested in this thread) but when I run the main progam I got the following exception:
WARN - NativeCodeLoader - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ERROR - Shell - Failed to locate the winutils binary in the hadoop binary path
Exception in thread "main" java.net.ConnectException: Call From EL-OUED/192.168.2.8 to 192.168.2.216:8020 failed on connection exception: java.net.ConnectException: Connection refused: no further information; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

Also, when checking connection configuration on hadoop, it seems it is listening/accepting for connections on 127.0.0.1:8020.
$netstat -lent | grep 8020
tcp 0 0 127.0.0.1:8020 0.0.0.0:* LISTEN 1001 10380
This is the content of core-site.xml, I wonder if it is the source of this problem and how to fix it?
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost</value>
</property>
</configuration>
Basically your namenode is listening on the localhost interface, therefore it allows connections only from 127.0.0.1. As you suggested, the error is indeed in the fs.default.name parameter, which should be modified to use the hostname instead of localhost.
Beware that /etc/hosts should contain a line like
192.168.2.216 hostname.fully.qualified.domain.com hostname
You can verify that the hostname is properly setting running the command "hostname" and "hostname -f". "hostname" should return the the name of the system as returned by gethostname, while "hostname -f" should return the fqdn of the system.
I downloaded the Smack example code to send GCM to Android devices from a server.
When I run it on my dev machine I get a Smack debugging window.
On my server I get this:
Exception in thread "Thread-6" java.lang.IllegalArgumentException: Can't initialize the configured debugger!

How do I disable the Smack debug window?
After I go
myConfig = new ConnectionConfiguration(SERVER, PORT);
I have to go
myConfig.setDebuggerEnabled(false);
