------------------------------------
Summary: MockTable's addMutation does not check for empty mutation
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
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.
