bq. TEST-org.apache.hadoop.hbase.master.TestDistributedLogSplitting.xml.<init>
Don't think it is related test failure. Will commit now. Thanks for the
reviews Stack and Ram.

> While writing Cells to this stream, to make the CellBlock ByteBuffer, we do
> write length of the cell as int. We use StreamUtils to do this which will
> write each byte one after the other. So 4 write calls on Stream.(OutputSteam
> has only this support) With ByteBufferOuputStream we have the overhead of
> checking for size limit and possible grow with every write call. Internally
> this stream writes to a ByteBuffer. Again inside the ByteBuffer
> implementations there is position limit checks. If we do write these length
> as int in one go we can reduce this overhead.
