Subject [jira] Created: (HBASE-2192) Failed commit due to NotServingRegionException makes further transactions fail with UnknownTransactionException
Date Sun, 07 Feb 2010 17:08:28 GMT
Failed commit due to NotServingRegionException makes further transactions fail with UnknownTransactionException
---------------------------------------------------------------------------------------------------------------

                 Key: HBASE-2192
                 URL: https://issues.apache.org/jira/browse/HBASE-2192
             Project: Hadoop HBase
          Issue Type: Bug
          Components: contrib
    Affects Versions: 0.20.3
         Environment: OpenSolaris, java 1.6.0_10, pseudo-distributed setup; Hadoop 0.20.1
and HBase 0.20.3, single java client, Hadoop dfs.replication=1, HBase configured to use transactional
server.
            Reporter: Jesse Hallio


After a commit has failed with org.apache.hadoop.ipc.RemoteException: org.apache.hadoop.hbase.NotServingRegionException:
db,,1265553236583 (see HBASE-2191 for more information) any further transactions to the same
table fail. (other tables untested)

Waiting for ~10 hours doesn't seem to clear the situation, neither does calling truncate and
major_compact on the table and major_compact on .META.. only known way to resolve the situation
is to restart hbase.
