Subject [jira] [Commented] (ACCUMULO-2918) replication makes tservers quit
Date Tue, 17 Jun 2014 15:43:03 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2918?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14033933#comment-14033933

Sean Busbey commented on ACCUMULO-2918:
---------------------------------------

the [Master class has a function upgradeZooKeeper|https://github.com/apache/accumulo/blob/master/server/master/src/main/java/org/apache/accumulo/master/Master.java#L278]
that handles these kinds of changes.

Right now, it looks like in master we still have the 1.5 -> 1.6 upgrade code in place.
In fact, [we still have the persisted version set to 6|https://github.com/apache/accumulo/blob/master/server/base/src/main/java/org/apache/accumulo/server/ServerConstants.java#L50],
so no upgrade code will run when moving from 1.6 to 1.7.

Sounds like we need to [decide what our general upgrade policy is going to be moving forward
(see the mailing list thread on upgrades)|http://mail-archives.apache.org/mod_mbox/accumulo-dev/201406.mbox/%3CCAGHyZ6Lv6QQ2PwtckQoUkEBD1DP1K69SO-n0aCQSUeMzmDnTeQ%40mail.gmail.com%3E]
and then update the upgrade code accordingly.
