[jira] [Resolved] (HBASE-11164) Document and test rolling updates from 0.98 -> 1.0

     [ https://issues.apache.org/jira/browse/HBASE-11164?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-11164.
---------------------------
      Resolution: Fixed
    Hadoop Flags: Reviewed

I just ran the roling upgrade script and it worked.  Did on small cluster.  No exceptoins in logs other than expected when RSs go away for a while as they are rolling graded.  Did this after changing symlink to point at new software:

HADOOP_HOME=~/hadoop-2.6.0-CRC-SNAPSHOT ~/hbase/bin/rolling-restart.sh --config ~/conf_hbase

Add more doc into upgrade on what a rolling upgrade is and added some to the 0.98 to 1.0 section.

Resolving as done.

> I think 1.0 should be rolling upgradable from 0.98 unless we break it intentionally for a specific reason. Unless there is such an issue, lets document that 1.0 and 0.98 should be rolling upgrade compatible. 
> We should also test this before the 0.99 release.
