Hi, I'm a noob user with Zeppelin. In order to do distributed computing, I've installed Spark cluster on EC2 (with master & 5 slaves) and make Zeppelin server to refer the Spark master. I've tried to set master url at 'interpreter' menu in Zeppelin as following: spark://ec2-52-24-213-147.us-west-2.compute.amazonaws.com:7077 (Spark master url which is running on AWS with 5 slaves) And I also set export MASTER= in 'zeppelin-env.sh' as same.
However, when I run script on the notebook, the following error is occured: org.apache.zeppelin.interpreter.remote.RemoteInterpreter.interpret(RemoteInterpreter.java:221) org.apache.zeppelin.interpreter.LazyOpenInterpreter.interpret(LazyOpenInterpreter.java:93) org.apache.zeppelin.notebook.Paragraph.jobRun(Paragraph.java:212) org.apache.zeppelin.scheduler.Job.run(Job.java:170) org.apache.zeppelin.scheduler.RemoteScheduler$JobRunner.run(RemoteScheduler.java:296) java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) java.util.concurrent.FutureTask.run(FutureTask.java:262) java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:178) java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:292) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) java.lang.Thread.run(Thread.java:745) Could you give me some hints please? Best,
