Review request for Flume.
Bugs: FLUME-2338
https://issues.apache.org/jira/browse/FLUME-2338
Repository: flume-git
Description
-------
Coalesce support for HBaseSink. Also includes a BatchAware interface, allowing
serializers that implement it to be aware of batching so that they can choose
keys to optimize the effect of coalescing, if desired.

Testing
-------
Added unit tests. Tested a version of this patch (prior to a rebase for trunk)
under high load and the approach is very effective for certain high-increment
workloads that end up with a lot of contention on keys in HBase.
Thanks,
Mike Percy
