>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3, test
>    Affects Versions: 3.3.0
>            Reporter: Steve Loughran
>            Priority: Minor
>
> transient failure of ITestDynamoDBMetadataStore.testTableVersioning; the deleted table version record was still there.
> Looks like the delete is EC; finally I hit a consistency event
> Proposed: the test iterates a bit awaiting the exception
