I replaced hbase jar with hbase-0.90.1.jar I also upgraded client side jar to hbase-0.90.1.jar
Our map tasks were running faster than before for about 50 minutes. However, map tasks then timed out calling flushCommits(). This happened even after fresh restart of hbase. I don't see any exception in region server logs. In master log, I found: 2011-02-10 18:24:15,286 DEBUG org.apache.hadoop.hbase.master.handler.OpenedRegionHandler: Opened region -ROOT-,,0.70236052 on sjc1-hadoop6.X.com,60020,1297362251595 2011-02-10 18:24:15,349 INFO org.apache.hadoop.hbase.catalog.CatalogTracker: Failed verification of .META.,,1 at address=null; org.apache.hadoop.hbase.NotServingRegionException: org.apache.hadoop.hbase.NotServingRegionException: Region is not online: .META.,,1 2011-02-10 18:24:15,350 DEBUG org.apache.hadoop.hbase.zookeeper.ZKAssign: master:60000-0x12e10d0e31e0000 Creating (or updating) unassigned node for 1028785192 with OFFLINE state I am attaching region server (which didn't respond to stop-hbase.sh) jstack.
