Yup, I understand that's this issue (the fix is still unreleased):

However, my suspicion is that adding/removing nodes has probably
kickstarted the compaction anyway. I've tried issuing "nodetool
compact" with no obvious improvement. Also, there are plenty of
compactions running - it just seems like the number of pending tasks
is never affected.

Good point on the version. I'm on 2.0.1.
