I read this recently:
1.1.9 (also 1.2.1) * ... * nodetool repair command now prints progress (CASSANDRA-4767) * ... Not sure how it works, I am still using the 1.1.6 version of C* but you might be interested in reading this. https://github.com/apache/cassandra/blob/trunk/CHANGES.txt https://issues.apache.org/jira/browse/CASSANDRA-4767 Alain 2013/2/28 Michael Kjellman <mkjell...@barracuda.com> > There is no overall repair progress currently. > > You can use some awk/grep hackery to try and figure it out from the logs. > (This works best for a cleanup, less so for a repair because ranges are > skipped and merkel trees take a long time to compare/generate/validate) > > Remember, things might be streaming so also check netstats.
