Subject [jira] [Commented] (FLINK-8946) TaskManager stop sending metrics after JobManager failover
Date Thu, 15 Mar 2018 09:33:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16400126#comment-16400126

vinoyang commented on FLINK-8946:

Hi [~till.rohrmann] , about this issue I think we could :

init the instance of *TaskManagerMetricGroup* in method (if jm failover , we could have a
new instance):
and close the metric group in method :
at last, we can recheck and close in TaskManager's postStop method.

>             Project: Flink
>          Issue Type: Bug
>          Components: Metrics, TaskManager
>    Affects Versions: 1.4.2
>            Reporter: Truong Duc Kien
>            Assignee: vinoyang
>            Priority: Major
> Running in Yarn-standalone mode, when the Job Manager performs a failover, all TaskManager
that are inherited from the previous JobManager will not send metrics to the new JobManager
and other registered metric reporters.
> A cursory glance reveal that these line of code might be the cause
> [https://github.com/apache/flink/blob/a3478fdfa0f792104123fefbd9bdf01f5029de51/flink-runtime/src/main/scala/org/apache/flink/runtime/taskmanager/TaskManager.scala#L1082-L1086]
> Perhap the TaskManager close its metrics group when disassociating JobManager, but not
creating a new one on fail-over association ?
