hi; we have a 12 node cluster across 2 datacenters. We are currently using cassandra 2.1.12 version.
SNITCH : GossipingPropertyFileSnitch When we decommissioned few nodes in a particular datacenter and observed the following : nodetool status shows only the live nodes in the cluster. nodetool describecluster shows the decommissioned nodes as UNREACHABLE. nodetool gossipinfo shows the decommissioned nodes as "LEFT" When the live nodes were restarted, "nodetool describecluster" shows only the live nodes, which is expected. Purging the gossip info too did not help. INFO 17:27:07 InetAddress /X.X.X.X is now DOWN INFO 17:27:07 Removing tokens [125897680671740685543105407593050165202, 140213388002871593911508364312533329916, 98576967436431350637134234839492449485] for /X.X.X.X INFO 17:27:07 InetAddress /X.X.X.X is now DOWN INFO 17:27:07 Removing tokens [11116977666116265389022494863106850615, 111270759969411259938117902792984586225, 138611464975439236357814418845450428175] for /X.X.X.X Has anybody experienced similar behaviour. Restarting the entire cluster, everytime a node is decommissioned does not seem right. Thanks in advance for the help. thanks Sai
