Hi Ted,

I need to consult management on whether I am able to publish the code.

I might be able to publish a snippet of the code so I can get assistance.

Can you show your code involving usage of hbase.regionserver.impl ?

Please also show the full stack trace of NPE.

A quick check across 0.98, branch-1 and master doesn't reveal difference
around this config.
