I have already followed similar questions and answers but none of them helped me.
I have setup code on bit bucket, Integrated everything in jenkins. Added Chromedriver and Phantom JS pakage to folder /opt/
Added /opt/ permission to 777.
I tried to execute build with both [Chromedriver and Phantomjs] one by one but having same error.
Stack Trace :

I can run successfully in terminal window by command “mvn clean verify -Dcucumber.options="--tags #ValidateLoggedInUser"”
Because some the other test cases have error. So I need to debug to check the step and reason.
But there is error when run it in *.feature file.

I don't have problem with Hadoop. The installation and stating is OK.
I'm using Java 8 x64 (jdk1.8.0_92)
When I start Spark with the command spark-shell, I got the Java error bellow :

I get exactly the same stack trace when opening the scala console in Netbeans. If I type any scala expression below the stack trace, it works fine though.
I have just did a fresh install of Groovy 2.4.3 in OSX 10.10.3 by means of the GVM tool.
I also installed, using GVM, related libraries and tools such as groovyserv, grails and gradle.
The Java version I am using is 1.8.0_25.
Everything seems fine with the exception that I cannot start the Groovy Console by means of the command groovyConsole since I keep obtaining this exception:

What is the best way to fix this?
I had this one before and it was due to an environment classpath variable set to point to an invalid jar
I had also same issue. In my case JAVA_HOME path was wrong. So I set JAVA_HOME then its working without any problem.
After setting JAVA_HOME, its launched:

note: my current data base is a back up version that i restore in my cassandra!
thanks for your help :)
edit: i have two keyspace,A and B. B is a back up version that i restore and store more data on it, but A is not. i can create back up from A with out any problem,but for B i get above error!
this seems to be an ubuntu 12.04 security issue on hard-links.
use this command to disable that:
sudo sysctl -w kernel.yama.protected_nonaccess_hardlinks=0
and after restore, reset it to its original value:
sudo sysctl -w kernel.yama.protected_nonaccess_hardlinks=1
After struggling with this issue again I found that I had a few root-owned files inside /var/lib/cassandra/data/.../etcetera, which triggered the hard link access restriction.
Recursively chowning all directories and files inside /var/lib/cassandra/data solved the problem.
