Subject ERROR: org.apache.hadoop.hbase.client.NoServerForRegionException:
Date Fri, 06 Sep 2013 10:56:56 GMT
Hi,

I'm using cdh 4.2.0 and hbase 0.94.2. our cluster working on 12 nodes.

when I scan table in hbase shell or java api, it return:

ERROR: org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to
find region for <table_name>,,99999999999999 after 7 tries.

I am getting same exception when runnig "sudo -u hbase hbase hbck -repair".

One region looks unassigned in web ui and hbase zkcli.

my hbase master log:
