Subject [jira] [Commented] (FLINK-8946) TaskManager stop sending metrics after JobManager failover
Date Thu, 22 Mar 2018 00:06:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16408813#comment-16408813

vinoyang commented on FLINK-8946:
---------------------------------

Could I create a new issue ? It seems that closing mertics group is not this issue's core
problem. For this issue in TaskManager (non-flip 6) I provided a solution in my first comment.
What's your idea? Thanks. On 2018-03-22 04:04 , Till Rohrmann (JIRA) Wrote: [ https://issues.apache.org/jira/browse/FLINK-8946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16408492#comment-16408492
