Description

HBASE-14893 was brought to attention by rajeshbabu over PHOENIX-3111.

This issue is to consider reverting the fix from HBASE-14893 based on the following observations:

• The closing boolean was intended to be acquired before taking the lock (enis)
• Phoenix local index has evolved over the years, the situation leading to NotServingRegionException may not exist from Phoenix side
• Even if the situation still exists, downstream project (Phoenix) should properly handle NotServingRegionException without change in locking scheme in hbase
