> Key: PHOENIX-7422
> URL: https://issues.apache.org/jira/browse/PHOENIX-7422
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 5.2.0
> Reporter: Tanuj Khurana
> Assignee: Tanuj Khurana
> Priority: Major
>
> In TableTTLIT,
> testMinorCompactionShouldNotRetainCellsWhenMaxLookbackIsDisabled fails 90% of
> times on my workstation. On debugging, I found that the test fails when
> multiple updates happen to the same row within the same millisecond. When
> this happens, the latest update simply overwrites the cells of the previous
> update. This breaks the test.
