> ---------------------------------------------------
>
>                 Key: KUDU-801
>                 URL: https://issues.apache.org/jira/browse/KUDU-801
>             Project: Kudu
>          Issue Type: Bug
>          Components: tablet
>    Affects Versions: Private Beta
>            Reporter: Todd Lipcon
>            Priority: Critical
>
> I saw a case of mt-tablet-test failing with what I think is the following scenario:
> - transaction applies an update to DMS
> - delta flush happens
> - major delta compaction runs (the update is now part of base data and we have an UNDO)
> - the RS is selected for compaction
> - CHECK failure because the UNDO delta contains something that is not yet committed.
> We probably need to ensure that we don't Flush data which isn't yet committed from an MVCC standpoint.
