Subject Re: Read latency is over 1 minute on a column family with 400,000 rows

Looks like a broken node, just restart Cassandra on that node. Might want to 
wait for the compaction to finish on the other nodes.

Also, don't forget to JMX gc() manually after the compaction has finished to 
delete the files on each node.
