Subject [jira] [Created] (CASSANDRA-7803) When compaction is interrupted, it leaves locked, undeletable files
Date Wed, 20 Aug 2014 12:13:26 GMT
Scooletz created CASSANDRA-7803:

             Summary: When compaction is interrupted, it leaves locked, undeletable files
                 Key: CASSANDRA-7803
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: RedHat, xfs4, JNA enabled, JBOD,
            Reporter: Scooletz

During tests of new features of 2.1 like: 
- incremental repairs 
- leveled compaction
I interrupted a compaction, which left the following ERROR in the _system.log_
org.apache.cassandra.db.compaction.CompactionInterruptedException: Compaction interrupted:
Compaction@152e6e70-1975-11e4-ba09-61f0d75c60c6(xx, xxx, 378505918/1993581634)bytes

Right after that, a cascade of reoccurring errors was emitted:
ERROR [NonPeriodicTasks:1] 2014-08-19 13:38:41,258 - Unable to
delete /grid/data04/cassandra/data/xx/xxx-152e6e70197511e4ba0961f0d75c60c6/xx-xxx-ka-55058-Data.db
(it will be removed on server restart; we'll also retry after GC)
which made this node blinking (noted from the other nodes gossiper log entries).
After restart, the node is healthy and fully operational.
