NotServingRegionException in Pseudo-Distributed Mode
Bing Li 2012-04-11, 16:27
Dear all,

I got an exception as follows when running HBase. My Hadoop is set up in
the pseudo-distributed mode. The exception happens after the system runs
for about one hour.

The specification of NotServingRegionException says "thrown by a region
server if it is sent a request for a region it is not serving". I cannot
figure out how to solve it in my case.

Could you please help me on this?

Thanks so much!
Bing
