Subject [jira] [Commented] (FLINK-2213) Configure number of vcores
Date Mon, 09 Nov 2015 12:13:11 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14996423#comment-14996423

Fabian Hueske commented on FLINK-2213:

Flink does not give guarantees for the number of threads per task slot. Each unchained operator
runs as a thread and some operators such as sorts are executed in multiple threads.

Do you know what the termination condition of a {{LinuxContainerExecutor}} is?

>             Project: Flink
>          Issue Type: Improvement
>          Components: YARN Client
>    Affects Versions: 0.10
>            Reporter: Ufuk Celebi
> 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.
