Subject [jira] [Commented] (FLINK-10096) Metrics report incorrect subtask ids
Date Thu, 25 Oct 2018 14:27:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-10096?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16663806#comment-16663806

Chesnay Schepler commented on FLINK-10096:
------------------------------------------

I did not close it due to being low priority, but because I sincerely do not have any plans
to change the metric system as proposed here.

I'd rather change the string representation of stream-tasks since that is the inconsistent
part; it conflicts with the metric system, rest api and all(most?) logging messages that log
the subtask index .

> Subtask id is of by one when it's being reported by metrics compared to what is printed
by {{StreamTask.toString()}}. For example metrics line:
> Initial sorter.137.buffers.inputQueueLength: 392
> vs actual name of this subtask:
> Initial sorter (138/192)
