Hi, is there any way to determine that rebuild is complete
If you ran it from a screen ( https://www.gnu.org/software/screen/manual/screen.html) or similar stuff, you should see the command return. Also, 'nodetool netstats | grep -v 100%' will show you remaining stream. No stream = rebuild finish (look for possible errors in the logs though...). Last tip is you should be able to imagine how big the dataset is going to be and checking the on disk size give good progress information too. This is not really accurate though.
