Subject Region has been CLOSING for too long, this should eventually complete or the server will expire, send RPC again
Date Tue, 16 Apr 2013 01:51:35 GMT
Hi

 

I am a newer for hadoop, and set up hadoop with tarball . I have 5 nodes for
cluster, 2 NN nodes with QJM (3 Journal Nodes, one of them on DN node.  ), 3
DN nodes with zookeepers,  It works fine.  When I reboot one data node
machine which includes zookeeper, after that , restart all processes. The
hadoop works fine, but hbase not. I cannot disable tables and drop tables.

 

The logs an follows:

The Hbase HMaster log:

DEBUG org.apache.hadoop.hbase.master.AssignmentManager: Attempted to
unassign region -ROOT-,,0.70236052 but it is not currently assigned anywhere

,683 INFO org.apache.hadoop.hbase.master.AssignmentManager: Regions in

The Hbase HRegionServer log:

cachingAccesses=0, cachingHits=0, cachingHitsRatio=0, evictions=0,
evicted=0, evictedPerRun=NaN

 

The Hbase Web show:

Region                                              State

70236052    -ROOT-,,0.70236052 state=CLOSING, ts=Mon Apr 15 12:52:38 CST
2013 (75440s ago), server=Master,60000,1366001238313

 

How fix it?

 

Thanks.
