> Issue Type: Bug
> Reporter: Alan Boudreault

>
> During my hints storage benchmarks, I've experienced an issue using C* 2.2.
> The hints was never replayed. After a while (more than 24H ...), I noticed
> that there were still compactions running on system.hints and that some new
> ones was triggered every 10-20 minutes.
> To reproduce, we create a cluster of 2 nodes. RF=2 and we generate hints by
> shutting down the node2.
> {code}
> ccm create --install-dir=`pwd` -n 2 local && ccm start
> ccm node1 stress -- write n=50M -rate threads=300 -port jmx=7198 -errors
> ignore -schema replication\(factor=2\)
> # wait 5-6 seconds to get the schema creation propagated on all nodes, then
> in another window, stop node 2
> ccm node2 stop
> # wait the initial 50M writes are finished, bring back node2 up and write
> another 50M keys.
> ccm node2 start
> ccm node1 stress -- write n=50M -rate threads=300 -port jmx=7198 -errors
> ignore -schema replication\(factor=2\)
> # You should get the initial compaction finished after 15-20 minutes. You can
> set the mb throughput to 0 to get that done faster.
> # Monitor the node1. the hints will never be replayed and you should see
> compactions happening indefinitely.
