Subject Re: Detect Repair is finish

You can do this with two nodetool commands:
nodetool compactionstats will check on active Merkle Tree calculations.

nodetool netstats will list out any active repair streams.

Aaron Morton posted a Bash script/command a while back that you can just
paste into the (linux) command line to monitor active streams for you:

while true; do date; diff <(nodetool -h localhost netstats) <(sleep 5
&& nodetool -h localhost netstats); done

Hope this helps,
