Subject [jira] [Commented] (CASSANDRA-6618) NullPointerException while stopping/draining if native transport wasn't started
Date Fri, 24 Jan 2014 22:09:37 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13881470#comment-13881470

Brandon Williams commented on CASSANDRA-6618:
---------------------------------------------

I don't see how setting it to true after calling run() or calling it as the last step inside
run() makes any difference.
