When running a new Zeppelin, I got error like :
org.apache.zeppelin.interpreter.InterpreterException: java.io.IOException: Fail to detect scala version, the reason is:Cannot run program "null/bin/spark-submit": error=2, No such file or directory at org.apache.zeppelin.interpreter.remote.RemoteInterpreter.open(RemoteInterpreter.java:128) at org.apache.zeppelin.interpreter.remote.RemoteInterpreter.getFormType(RemoteInterpreter.java:270) at org.apache.zeppelin.notebook.Paragraph.jobRun(Paragraph.java:428) at org.apache.zeppelin.notebook.Paragraph.jobRun(Paragraph.java:68) at org.apache.zeppelin.scheduler.Job.run(Job.java:186) at org.apache.zeppelin.scheduler.AbstractScheduler.runJob(AbstractScheduler.java:135) at org.apache.zeppelin.scheduler.RemoteScheduler$JobRunner.run(RemoteScheduler.java:186) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:750) Caused by: java.io.IOException: Fail to detect scala version, the reason is:Cannot run program "null/bin/spark-submit": error=2, No such file or directory at org.apache.zeppelin.interpreter.launcher.SparkInterpreterLauncher.buildEnvFromProperties(SparkInterpreterLauncher.java:139) at org.apache.zeppelin.interpreter.launcher.StandardInterpreterLauncher.launchDirectly(StandardInterpreterLauncher.java:76) at org.apache.zeppelin.interpreter.launcher.InterpreterLauncher.launch(InterpreterLauncher.java:106) at org.apache.zeppelin.interpreter.InterpreterSetting.createInterpreterProcess(InterpreterSetting.java:856) at org.apache.zeppelin.interpreter.ManagedInterpreterGroup.getOrCreateInterpreterProcess(ManagedInterpreterGroup.java:66) at org.apache.zeppelin.interpreter.remote.RemoteInterpreter.getOrCreateInterpreterProcess(RemoteInterpreter.java:103) at org.apache.zeppelin.interpreter.remote.RemoteInterpreter.internal_create(RemoteInterpreter.java:153) at org.apache.zeppelin.interpreter.remote.RemoteInterpreter.open(RemoteInterpreter.java:125)To solve this. First, delete the zeppelin/conf/interpreter.json . Dont worry, it will generated after starting zeppelin-daemon.sh
Next, running the zeppelin, go to interpreter and configure SPARK_HOME path on both spark and spark-submit settings. Don’t forget to setup the python path as well. Hope this solve your problem!
