Attachment: accumulo1505.patch

> ---------------------------------------------------------

> Key: ACCUMULO-1505
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1505
> Project: Accumulo
> Issue Type: Bug
> Components: client
> Affects Versions: 1.4.3
> Reporter: Ryan Leary
> Fix For: 1.4.4, 1.5.1, 1.6.0
>
> Attachments: accumulo1505.patch

>
> When calling addMutation or addMutations on a MockBatchWriter, the updates
> stored in the mutation are iterated over then committed in the MockTable
> class.
> When this occurs in the TabletServerBatchWriter (eventually called from the
> BatchWriterImpl), however, the mutation size is first checked and if the
> mutation size is 0, an IllegalArgumentException is thrown.
> In practice, if you have code that tries to submit an empty mutation to a
> BatchWriter, it will fail and throw an exception in the real world, but this
> will not be caught in tests against MockAccumulo.
