> ---------------------------------------------------------------------

> Key: SPARK-4989
> URL: https://issues.apache.org/jira/browse/SPARK-4989
> Project: Spark
> Issue Type: Bug
> Components: Deploy, Spark Core
> Affects Versions: 1.0.0, 1.1.0, 1.2.0
> Reporter: Zhang, Liye
> Assignee: Zhang, Liye
> Priority: Critical
> Fix For: 1.3.0
>
>
> when enabling eventlog in standalone mode, if give the wrong configuration,
> the standalone cluster will down (cause master restart, lose connection with
> workers).
> How to reproduce: just give an invalid value to "spark.eventLog.dir", for
> example: *spark.eventLog.dir=hdfs://tmp/logdir1, hdfs://tmp/logdir2*. This
> will throw illegalArgumentException, which will cause the *Master* restart.
> And the whole cluster is not available.
> This is not acceptable that cluster is crashed by one application's wrong
> setting.
