[jira] [Updated] (HBASE-14523) rolling-restart.sh --graceful will
start regionserver process on master node
[ https://issues.apache.org/jira/browse/HBASE-14523?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Samir Ahmic updated HBASE-14523:
--------------------------------
Description:
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 above list.
