Subject [jira] [Created] (CASSANDRA-9580) Carnality check broken during incremental compaction re-opening
Date Thu, 11 Jun 2015 15:08:00 GMT
T Jake Luciani created CASSANDRA-9580:
-----------------------------------------

             Summary: Carnality check broken during incremental compaction re-opening
                 Key: CASSANDRA-9580
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9580
             Project: Cassandra
          Issue Type: Bug
            Reporter: T Jake Luciani
            Priority: Minor
             Fix For: 2.1.7
         Attachments: lcstest.yaml

While testing LCS I found cfstats sometimes crashes during compaction 

It looks to be related to the incremental re-opening not having metadata.
