> Key: HADOOP-16384
> URL: https://issues.apache.org/jira/browse/HADOOP-16384
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Fix For: 3.3.0
>
> Attachments: hwdev-ireland-new.csv

>
> HADOOP-15183 added detection and rejection of prune updates when the store is
> inconsistent (i.e. when it tries to update an entry twice in the same
> operation, the second time with one that is inconsistent with the first)
> Now that we can detect this, we should address it. We are lucky here in that
> my DDB table is currently inconsistent: prune is failing.
> Plan
> # new test to run in the sequential phase, which does a s3guard prune against
> the bucket used in tests
> # use this to identify/debug the issue
> # replicate the problem in the ITestDDBMetastore tests
> # decide what to do in this world. Tell the user to run fsck? skip?
