Date Wed, 13 Aug 2014 17:32:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14095762#comment-14095762

Jonathan Hsieh commented on HBASE-10202:

Good content, but here are some points to emphasize and a few nits to fix:

It should say that the rolling-restart.sh script is a good template for doing rolling restarts
and to make it clear that it is not explicitly tested.  Depending on your setup YMMV -- this
script depends on loginless ssh and assumes a tarball deployment.  It also requires some env
variables setup by the user executing the script.

+          RegionServers only.</para>
+        <example>

The new version has at least one inadvertent merge problems.
