Hari Shreedharan commented on FLUME-2338:
-----------------------------------------

Mike,

This looks good. This unfortunately is not compatible with HBase 0.96.x. In the HBase 96 branch, the method to get the family map is:
getFamilyMapOfLongs()
(https://github.com/apache/hbase/blob/0.96/hbase-client/src/main/java/org/apache/hadoop/hbase/client/Increment.java#L168 )

We probably should use reflection to call the correct method, but the getFamilyMapOfLongs()  looks like an expensive operation though. I am not sure if there is a way around it though.

> Support coalescing increments in HBaseSink
> If a batch has multiple increments to the same row/column, these can be coalesced into a single HBase RPC call.
