Subject [jira] [Commented] (HBASE-11164) Document and test rolling updates from 0.98 -> 1.0
Date Fri, 24 Oct 2014 02:24:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14182330#comment-14182330

stack commented on HBASE-11164:
-------------------------------

There is no support in 0.96 for HBASE-4811 Support reverse Scan.  It was backported to 0.94
but not to 0.96.  HBASE-10018 Remove region location prefetching added making use of reverse
scanning doing lookups against meta.  This makes it so we cannot do a rolling restart from
0.96 to 1.0.  Let me add note to refguide.

> 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.
