Vrushali C updated YARN-6874:
-----------------------------
Labels: atsv2-hbase (was: )
> Supplement timestamp for min start/max end time columns in flow run table to
> avoid overwrite
> --------------------------------------------------------------------------------------------

> Key: YARN-6874
> URL: https://issues.apache.org/jira/browse/YARN-6874
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Reporter: Varun Saxena
> Assignee: Vrushali C
> Labels: atsv2-hbase
> Fix For: YARN-5355, YARN-5355-branch-2
>
> Attachments: YARN-6874-YARN-5355.0001.patch
>
>
> Following test case is failing in YARN-5355 branch.
> This is coming because we are not supplementing the timestamp for
> FlowRunColumn i.e. min_start_time and max_end_time columns, post YARN-6850
> which can lead to a clash, if 2 writes for app created events happen at the
> same time, which is true for this test case.
> To fix this, we need to pass true flag into ColumnHelper constructor. I did
> encounter this failure once earlier too.
