Subject graceful_stop.sh hung
Date Wed, 08 Jan 2014 11:57:56 GMT
Hi, all
  I restart a region server by using graceful_stop.sh (bin/graceful_stop.sh --restart --reload
--debug hostname), when running a moment, the process hanging as follows:

  I run ‘du' command to check the last region , which  has not any data.
hadoop@inspur249:~/hbase$ hdfs dfs -du -s -h /hbase/test/812912be704946d24c5f1b5e3184b2f5/*
486  /hbase/test/812912be704946d24c5f1b5e3184b2f5/.regioninfo
0  /hbase/test/812912be704946d24c5f1b5e3184b2f5/body
0  /hbase/test/812912be704946d24c5f1b5e3184b2f5/meta

hadoop version is cdh4.2.1 and hbase is 0.94

Thanks!
Best Regards~
