[jira] Commented: (CASSANDRA-491) Hinted HandOff doesn't work for
SuperColumnFamilies
[ https://issues.apache.org/jira/browse/CASSANDRA-491?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12766605#action_12766605 ]
Jonathan Ellis commented on CASSANDRA-491:
------------------------------------------
02
Avoid using non-existent supercolumn timestamp in delete op. Better conceptual integrity to delete w/ correct system time anyway
01
fix HH of tombstones
this should fix the problem w/o having to manually clear out old data.
