Hi,
We got a Map/Reduce job that threw NotServingRegionException when the reducer
was about to insert data into a Hbase table. The error message is as follows.
I also copied the corresponding region server log at the end of the message.
Also, we browsed through the hbase administrative page
Sorry I pasted the wrong portion of the region server log. The right portion
should be as follows:
==

Hello sir,
A possible reason could be, your client is contacting the given
regionserver, and that regionserver kept on rejecting the requests.
Are you sure your table and all regions online? Use hbck once and see
if you find anything interesting.

Thanks. But if we do a scan on the table via the hbase shell, data in the
table did show up.

hbck should help expose more problems than a single scan would. With that
said the logs are the best bet in understanding what is going on with the
cluster at the time of the issue. You posted logs that seem to only really
contain GC info. Do you have more information about the cluster state
Besides GC info, the master log is as follows.
