Subject Re: How to Restore the block locality of a RegionServer ?

First, understand why you had to create an ‘auto restart’ script. 

Taking down HBase completely (probably including zookeeper) and do a full restart would probably
fix the issue of data locality.

purely accidental. 
Use at your own risk.
