major compaction

Hello,

When I do a major compaction of a table (1 billion rows). How do I know
when its completed? Also, what can I see in the metrics to see the status
of it

Your best bet - short of tailing the logs - seems to use the compactionQueue metric, that is available through Ganglia and JMX. It should go back to zero when all compactions are done.
