All: I have some code that worked fine in Zeppelin 0.7.4 but I am having issues in 0.8.2 when going from spark master of local to yarn-client. Yarn client worked in 0.7.4.
When my master is set to local[*] it runs just fine. However, as soon as I switch to yarn-client I get the Cannot call methods on a stopped SparkContext error. In looking at my yarn logs everything creates fine and the job finishes without an error. The executors start just fine from what I get out of yarn logs. Any suggestions on where to look? This happens with any note that trys to run spark. If I try this very simple code: // Spark Version spark.version I get this error: java.lang.IllegalStateException: Spark context stopped while waiting for backend at org.apache.spark.scheduler.TaskSchedulerImpl.waitBackendReady(TaskSchedulerImpl.scala:614) at org.apache.spark.scheduler.TaskSchedulerImpl.postStartHook(TaskSchedulerImpl.scala:169) at org.apache.spark.SparkContext.<init>(SparkContext.scala:567) at org.apache.spark.SparkContext$.getOrCreate(SparkContext.scala:2313) at org.apache.spark.sql.SparkSession$Builder$$anonfun$6.apply(SparkSession.scala:868) at org.apache.spark.sql.SparkSession$Builder$$anonfun$6.apply(SparkSession.scala:860) at scala.Option.getOrElse(Option.scala:121) at org.apache.spark.sql.SparkSession$Builder.getOrCreate(SparkSession.scala:860) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.zeppelin.spark.BaseSparkScalaInterpreter.spark2CreateContext(BaseSparkScalaInterpreter.scala:259) at org.apache.zeppelin.spark.BaseSparkScalaInterpreter.createSparkContext(BaseSparkScalaInterpreter.scala:178) at org.apache.zeppelin.spark.SparkScala211Interpreter.open(SparkScala211Interpreter.scala:89) at org.apache.zeppelin.spark.NewSparkInterpreter.open(NewSparkInterpreter.java:102) at org.apache.zeppelin.spark.SparkInterpreter.open(SparkInterpreter.java:62) at org.apache.zeppelin.interpreter.LazyOpenInterpreter.open(LazyOpenInterpreter.java:69) at org.apache.zeppelin.interpreter.remote.RemoteInterpreterServer$InterpretJob.jobRun(RemoteInterpreterServer.java:616) at org.apache.zeppelin.scheduler.Job.run(Job.java:188) at org.apache.zeppelin.scheduler.FIFOScheduler$1.run(FIFOScheduler.java:140) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) What am I missing? -- ========= mailto:db...@incadencecorp.com ============ David W.
