Samir Ahmic created HBASE-14523:
-----------------------------------
Summary: rolling-restart.sh --graceful will start regionserver
process on master node
Key: HBASE-14523
URL: https://issues.apache.org/jira/browse/HBASE-14523
Project: HBase
Issue Type: Bug
Components: scripts
Affects Versions: 2.0.0
Reporter: Samir Ahmic
Assignee: Samir Ahmic
Fix For: 2.0.0
In master branch master acts also as regionserver hosting 'hbase:meta' table
and it has ephemeral znode created in '/hbase/rs'. Because of this
rolling-restart.sh --graceful will pick up master server from zk at this line:
{code}
online_regionservers=`$bin/hbase zkcli ls $zkrs 2>&1 | tail -1 | sed "s/\[//" |
sed "s/\]//"`
{code}
and will restart it a long with rest of regionservers.
I'm planing to add some code to rolling-restart.sh script to filter master
server from list above.
