Subject [jira] [Commented] (FLINK-1550) Show JVM Metrics for JobManager
Date Wed, 29 Jun 2016 17:10:17 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15355493#comment-15355493

ASF GitHub Bot commented on FLINK-1550:

Github user zentol commented on the issue:

    That is a known and intended behavior. It is the users responsibility to make sure that
no naming conflicts arise, either by providing unique job/task/operator names or modifying
the scope formats.
    Regarding your suggestion, even if we exclude the disparity between the name a user expects
and the name we might provide, there is still the issue that it (sadly) doesn't actually solve
    Assume 2 TaskManagers, both exporting a metric `MyJob.metric` and `MyJob1.metric`.
    You cannot guarantee that both versions of `MyJob.metric` actually belong to the same
    You can't even make the guarantee that all values a TM exposes as `MyJob.metric` belong
to a single job.
    This problem also exists right; the only difference is that you only have 1 set of inconsistent
data, and not 2.
