> After upgrading from cassandra 2.0.x to 2.1.10, we began seeing problems where some nodes
break the 12G commit log max we configured and go as high as 65G or more. Once it reaches
this state, "nodetool compactionstats" hangs. I watched the recovery live when compactions
begin happening again. the "nodetool compactionstats" suddenly completed to show the outstanding
jobs most in 100% completion state:

in system.log on the StatusLogger thread until after the compaction started working again.
