Subject [jira] [Created] (CASSANDRA-12186) anticompaction log message doesn't include the parent repair session id
Date Wed, 13 Jul 2016 06:48:20 GMT
Wei Deng created CASSANDRA-12186:
------------------------------------

             Summary: anticompaction log message doesn't include the parent repair session
id
                 Key: CASSANDRA-12186
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12186
             Project: Cassandra
          Issue Type: Bug
          Components: Observability
            Reporter: Wei Deng
            Priority: Minor


It appears that even though incremental repair is now enabled by default post C*-3.0 (which
means at the end of each repair session, there is an anti-compaction step that needs to be
executed), we don't include the parent repair session UUID in the log message of the anti-compaction
log entries. This makes observing all activities related to an incremental repair session
to be more difficult. See the following:

The initial submission of the anti-compaction task to the CompactionManager still has reference
to the parent repair session UUID, but subsequent anti-compaction log entries are missing
this parent repair session UUID.
