Subject [jira] [Commented] (CASSANDRA-7727) exception in CompactionExecutor after upgrade to trunk
Date Fri, 08 Aug 2014 20:15:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14091233#comment-14091233
] 

Russ Hatch commented on CASSANDRA-7727:
---------------------------------------

[~jbellis] that's definitely possible because the tests are starting and stopping nodes through
the upgrades. If this is a normal exception during shutdown, I assume that's probably the
case.
