I have a hbase table with with a wide row almost 2K columns per row. Each
KV size is approx 2.1KB
I have populated this table with generated hfiles using a MR job.
There are no write or mutate operations performed on this table.

Hi Ted,
Please find my answers below.
*Relase of Hbase:* 1.0.0-cdh5.4.1
*Configuration Change Before Restart:* Changed Block Cache related
configuration (mainly increased off heap bucket cache size)
*Compaction Gone means:* Yes Data locality became poor after restart.
Please find log snippet
Please change permission for other files owned by aparsh as well.

Can you provide us more information:
Release of HBase you use
Configuration change you made prior to restarting
By 'compaction is gone', do you mean that locality became poor again ?
