Subject [jira] [Commented] (ACCUMULO-2918) TServers expect zookeeper to have parent nodes created
Date Wed, 18 Jun 2014 18:16:25 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2918?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14036068#comment-14036068
] 

Keith Turner commented on ACCUMULO-2918:
----------------------------------------

Its nice for the upgrade code to be in one place makes it easier to understand when an upgrade
does and later remove the code when its no longer needed. We discussed not making upgrades
automatic to cover the case where someone accidently starts a newer version of Accumulo when
they do not actually want to upgrade.  In this case if someone accidentally starts a 1.7.0
tablet server on a 1.6.0 cluster, it may add this node in zookeeper?
