Subject [jira] [Created] (CASSANDRA-13142) Upgradesstables cancels compactions unnecessarily

----------------------------------------

             Summary: Upgradesstables cancels compactions unnecessarily
                 Key: CASSANDRA-13142
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13142
             Project: Cassandra
          Issue Type: Bug
            Reporter: Kurt Greaves
            Priority: Minor


Since at least 1.2 upgradesstables will cancel any compactions bar validations when run. This
was originally determined as a non-issue in CASSANDRA-3430 however can be quite annoying (especially
with STCS) as a compaction will output the new version anyway. Furthermore, as per CASSANDRA-12243
it also stops things like view builds and I assume secondary index builds as well which is
not ideal.

We should avoid cancelling compactions unnecessarily.

I'd class this as a very minor bug, should at least be fixed from 3.0, but up for debate.
The main negative effect is annoying operators (which I tend to rate pretty highly), but other
than that there are no serious consequences.
