Subject Re: NoServerForRegion Exception
Date Tue, 17 Nov 2009 16:06:33 GMT
Grep the region temp_table,,1258460379941 in your master log.  Try and
figure what happened to it.  Meantime, try closing it to see if that brings
it back online.  In the shell do:

hbase> close_region 'temp_table,,1258460379941'

Watch the master logs to see it transition.
