Re: regionserver restart ERROR
Ted Yu 2013-01-01, 05:26
region t113,,1356955542345.5f083a03434e02cc8ec1be0dc095b01b. was stuck in
PENDING_OPEN state on hadoop2,60020

Can you get log related to this region from hadoop2 ?

You might be experiencing https://issues.apache.org/jira/browse/HBASE-6060

Cheers
