Ted Yu updated HBASE-4079:
--------------------------

    Fix Version/s: 0.92.0
     Release Note: 
HTableUtil provides the following helper methods:
{code}
public static void bucketRsPut(HTable htable, List<Put> puts) throws IOException
{code}
It processes a List of Puts and writes them to an HTable instance in RegionServer buckets
via the htable.put method.
{code}
public static void bucketRsBatch(HTable htable, List<Row> rows) throws IOException
{code}
Processes a List of Rows (Put, Delete) and writes them to an HTable instance in RegionServer
buckets via the htable.batch method.

> A pattern that we use at Explorys is to chunk up Puts, and then bucket Puts by RegionServer.
 This reduces the number of RPC calls per writeBuffer flush, because the flushes will typically
be going to one region with this approach.
> I didn't think adding such utility methods to HTable was the right approach, so I created
an HTableUtil (in the .client package) that contained such functionality.
