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 transition timed out: -ROOT-,,0.70236052 state=CLOSING, ts=1366001558865, server=Master,60000,1366001238313 ,683 INFO org.apache.hadoop.hbase.master.AssignmentManager: Region has been CLOSING for too long, this should eventually complete or the server will expire, send RPC again 10,684 DEBUG org.apache.hadoop.hbase.master.AssignmentManager: Starting unassignment of region -ROOT-,,0.70236052 (offlining) The Hbase HRegionServer log: DEBUG org.apache.hadoop.hbase.io.hfile.LruBlockCache: Stats: total=7.44 MB, free=898.81 MB, max=906.24 MB, blocks=0, accesses=0, hits=0, hitRatio=0, 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.
