[jira] [Commented] (FLINK-3369) RemoteTransportException should be instance of CancelTaskException

["Stephan Ewen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-3369?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15137137#comment-15137137 ] 

Stephan Ewen commented on FLINK-3369:
-------------------------------------

In the long run, I think it makes sense that this exception is reported to the JobManager.

We can use this to learn that the source task manager has a problem, and not deploy further tasks to it unless it has pinged back, for example.

> {{RemoteTransportException}} is thrown when a consuming task is notified about failure at the producer side. This should not be reported as the root cause of the job failure. By making it an instance of {{CancelTaskException}} it will not be reported as a failure, but as a cancellation.
