stack updated HBASE-748:
------------------------
Attachment: hbase-748-v4.patch
Problem was deserializing the BatchUpdate, we'd use the no-arg BatchUpdate
constructor. The no-arg BatchUpdate waterfalls down to the constructor that
takes all arguments. It did this:
{code}
this.size = row.length;
{code}
If no-arg constructor, row was null. The NPE wasn't making it out during
deserialization.
This attached patch includes fix and some little cleanup.
> Add an efficient way to batch update many rows

> HBASE-747 introduced a simple way to batch update many rows. The goal of this
> issue is to have an enhanced version that will send many rows in a single RPC
> to each region server. To do this, the client code will have to figure which
> rows goes to which server, group them accordingly and then send them.
