Subbu M Iyer updated HBASE-5715:
--------------------------------

    Attachment: patch1.patch

1. Completely removed the monitoring code. The thought is since schema change 
is supposed to happen rather quickly we dont get much from the monitoring 
capability. We can add it later if there is a real need for same.

2. Added a rudimentary throttling when the RS  closes/opens the regions.

3. Increased the sleep time during concurrent split plus schema change 
executions.
