Subject Re: nodetool compactionstats doesn't work for repair status?
Date Thu, 28 Feb 2013 16:17:28 GMT
It reports what keyspace it is working on to stdout and when the ranges for that keyspace are
all in sync. It is a very welcome feature but doesn't really give an accurate status other
than when it started and finished repairing the keyspace in question.

Not sure how it works, I am still using the 1.1.6 version of C* but you might be interested
in reading this.

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. If that's not the case check for
exceptions that might have occurred and killed the repair job in your logs.

Also- nodetool just submits the jmx task. It isn't really a great indication (with ps as you
checked) to see if a repair has finished. (In a perfect 1.2.2 world this is kind of untrue,
but obviously there is lots of room for improvement here).

Best,
Michael

 How do I know if it is hung?  When I run "nodetool compactionstats" it shows nothing like
so
