Jeremiah Jordan commented on CASSANDRA-5898:
--------------------------------------------
I wasn't able to repro in 1.2. Once difference I noticed was that in 1.1
compactionstats I would see the "cleanup" and "regular" compactions running in
concurrently, but I never saw that in 1.2.
> nodetool cleanup interacting badly with LCS
