Subject [jira] [Commented] (REEF-1278) IFailedEvaluator message leads to shutting down of JAVA side driver
Date Fri, 25 Mar 2016 01:27:25 GMT

    [ https://issues.apache.org/jira/browse/REEF-1278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15211252#comment-15211252
] 

Julia commented on REEF-1278:
-----------------------------

I see what happened. 

getCause(0 for failed Evaluator at Java always returns null. In FailedEvaluatorHandler in
the testing, when client is trying to get cause, it throw null pointer exception, causing
a real failure and shut down. 

The PR for REEF-1280 removed getCause() call and use getEvaluatorException().getLocalizedMessage()
instead. If this is the root cause, the issue should be resolved by merging REEF-1280.

> Currently, when an evaluator fails and we get a IFailedEvaluator message in C# driver,
the Java side driver shuts itself down.
> This was not happening earlier and seems to have happened recently in last 1 month or
so.
> The aim of JIRA is to to fix this issue.
