Hi We monitor the number of pending tasks and in our dev cluster (size of 3), for two out of three nodes, the # of pending tasks did not decrease until I restarted cassandra on those two nodes. This is not the first time I saw this behavior. It is Saturday today and the traffic is very little.
nodetool compactionstats pending tasks: 5 Active compaction remaining time : n/a I have read http://comments.gmane.org/gmane.comp.db.cassandra.user/30555 but the comments were derailing in some way. I found nothing unusual in the log file. Like I said I restarted two of the nodes with the high count and then the count has gone down to 0. We are on 1.2.16. Thanks. John
