Subject [jira] [Commented] (FLINK-2213) Configure number of vcores
Date Tue, 10 Nov 2015 09:50:10 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14998321#comment-14998321

Maximilian Michels commented on FLINK-2213:

Seems to be more likely the container was killed due to memory usage.

Thanks for clarifying that every non-chained operator has its own thread [~fhueske]. Still,
setting the vcores to the number of task slots seems like a much better estimate to me than
defaulting to 1.

> Currently, the number of vcores per YARN container is set to 1.
> It is desirable to allow configuring this value. As a simple heuristic it makes sense
to at least set it to the number of slots per container.
