Subject [jira] Commented: (CASSANDRA-1414) Upgrade from 0.6 to 0.7 is bumpy if you have hints
Date Fri, 20 Aug 2010 19:02:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12900827#action_12900827
] 

Jonathan Ellis commented on CASSANDRA-1414:
-------------------------------------------

can we name the method something like purgeIncompatibleHints (so it doesn't imply we blow
away all hints at startup), and include in the log message that they are snapshotted in case
they need to roll back?  (I see you included it in NEWS already.)
