I am experiencing problems when restarting a cluster with hadoop/hbase 0.18.0. hadoop restarts OK, however hbase regionservers all exit with the message : Exception in thread "regionserver/0:0:0:0:0:0:0:0:60020" java.lang.NullPointerException at org.apache.hadoop.hbase.regionserver.HRegionServer.run(HRegionServer.java:448) at java.lang.Thread.run(Thread.java:619) strange enough, the said line appears to indicate log is null, however a log is created and messages are written into it... the restart scenario is very simple, and it happens even with a clean database , on a newly formatted FS. I have also checked no ghost processes exist before start.
"$INSTALLDIR/$HBASE/bin/stop-hbase.sh;$INSTALLDIR/$HADOOP/bin/stop-dfs.sh;" "$INSTALLDIR/$HADOOP/bin/start-dfs.sh;$INSTALLDIR/$HBASE/bin/start-hbase.sh;" any ideas ? -- View this message in context: http://www.nabble.com/problem-restarting-0.18-tp19671584p19671584.html Sent from the HBase User mailing list archive at Nabble.com.
