I am trying to follow the Documentation of Elastic Search to get and post data from it using its java Api's. But i am constantly getting error.
This is the code i have tried as of now.
Settings settings = Settings.builder().put("twitter", "tweet").build();
TransportClient client = new PreBuiltTransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300))
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300));
GetResponse response = client.prepareGet("twitter", "tweet", "1").get();
The stack trace

You miss the google-collections.jar in your classpath. Add it and the error will go away.
If you are using maven as dependency Management tool, add the follwing lines to your pom.xml:
<dependency>
<groupId>com.google.collections</groupId>
<artifactId>google-collections</artifactId>
<version>1.0</version>
</dependency>
Next jar is missing add lucene-core-<version>.jar
maven dependency is:
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-core</artifactId>
<version>6.5.1</version>
</dependency>

I have seen on the internet that Logging class exist only in spark 1.5.2 and lower versions.
Is there is any solution to make that work even with Spark 2.0.2 ?

I have the following folder structure
base directory = "."
build directory (for classes) = "./build/classes"
build directory (for test classes) = "./build/test/classes"
source = "./src"
test = "./test"
test_libraries = "./test_libraries"
everything works fine When I am running the test files with the command
java -cp /usr/share/java/junit4-4.11.jar:build/classes:build/test/classes/ org.junit.runner.JUnitCore myclass.MyClassTest
but when I change the location of the juint file to test_libraries/junit4-4.44.jar
and I run the command
java -cp ./test_libraries/junit4-4.11.jar:build/classes:build/test/classes/ org.junit.runner.JUnitCore myclass.MyClassTest
I get the following errors

You need Hamcrest on your classpath.
You are missing Hamcrest Jar
http://search.maven.org/remotecontent?filepath=org/hamcrest/hamcrest-core/1.3/hamcrest-core-1.3.jar
JUnit depends on Hamcrest for a lot of methods.
When i run command ./runExamples.sh on terminal it throws an exception. I have checked that Java is installed and class path is already set. How to resolve this?
