--------------------------------------
Reviewers: Sagar Sumit
> rollback of a partially failed commit which has new partitions fails with
> metadata table
> ----------------------------------------------------------------------------------------
>
> Key: HUDI-2712
> URL: https://issues.apache.org/jira/browse/HUDI-2712
> Project: Apache Hudi
> Issue Type: Sub-task
> Affects Versions: 0.10.0
> Reporter: sivabalan narayanan
> Assignee: sivabalan narayanan
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 0.10.0
>
>
> When a commit is being rolledback, and the commit has new partitions which
> was not present in the table before, files pertaining to this new partition
> may not be part of rollback plan. and so these files will be end up dangling
> w/o being cleaned up.
>
> Eg:
> commit 1: p1 (5 files) p2(5 files)
> commit2: p1(3 files) p2(3 files) p3(2 files) partial failed write.
>
> when commit3 is triggered, it will rollback commit2
> when generating rollback plan, we first fetch all partitions from
> TableFileSystemView which will hit metadata table when enabled.
> This may return only p1 and p2 and not p3(since commit2 is not completed)
> and then we do fs.list and filter out files that matches the commit2.
> So, in this case, we might miss to rollback the files added to p3.
