[jira] [Commented] (HBASE-5314) Gracefully rolling restart region servers in rolling-restart.sh

["stack (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-5314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13198024#comment-13198024 ] 

stack commented on HBASE-5314:
------------------------------

This is interesting.  You are putting together rolling_restart.sh and graceful_stop.sh.  Nice.

What version of hbase you working against?

Should this new behavior be optional otherwise those who might be using rolling_restart.sh now might get a surprise (IMO, its unlikely anyone is using rolling_restart.sh because it so disruptive.. which you are fixing... but still, I'd think a --graceful option that enables this new facility would be way to go).

Patch looks good but for this.

> The rolling-restart.sh has a --rs-only option which simply restarts all region servers in the cluster.
> Consider improve it to gracefully restart region servers to avoid the offline time of the regions deployed on that server, and keep the region distributions same as what it was before the restarting.
