[jira] Commented: (CASSANDRA-2309) Scrub resulting in "Keys must be
written in ascending order" exception
[ https://issues.apache.org/jira/browse/CASSANDRA-2309?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13005264#comment-13005264 ]
Jonathan Ellis commented on CASSANDRA-2309:
-------------------------------------------
Well, it's right -- the "current key" sorts before the "last written key" so it's out of order.
If scrub is able to continue, then you should probably do an sstable2json, then let scrub go ahead and strip out those out-of-order keys, then use the log messages to pull the keys that were out of order out of your json dump.
