vin01 commented on CASSANDRA-11919: ----------------------------------- Replication Factor : 2 for DC1 and 1 for DC2. CREATE KEYSPACE KEYSPACE_NAME WITH replication = {'class': 'NetworkTopologyStrategy', 'DC1': '2', 'DC2': '1'} AND durable_writes = true; I was able to remove the node with 'removenode' but it left cluster inconsistent and i had to perform a full repair on all keyspaces to fix that. > Failure in nodetool decommission > -------------------------------- > > Key: CASSANDRA-11919 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11919 > Project: Cassandra > Issue Type: Bug > Components: Streaming and Messaging > Environment: Centos 6.6 x86_64, Cassandra 2.2.4 > Reporter: vin01 > Priority: Minor > Fix For: 2.2.x > > > I keep getting an exception while attempting "nodetool decommission". > {code} > ERROR [STREAM-IN-/[NODE_ON_WHICH_DECOMMISSION_RUNNING]] 2016-05-29 > 13:08:39,040 StreamSession.java:524 - [Stream > #b2039080-25c2-11e6-bd92-d71331aaf180] Streaming error occurred > java.lang.IllegalArgumentException: Unknown type 0 > at > org.apache.cassandra.streaming.messages.StreamMessage$Type.get(StreamMessage.java:96) > ~[apache-cassandra-2.2.4.jar:2.2.4] > at > org.apache.cassandra.streaming.messages.StreamMessage.deserialize(StreamMessage.java:57) > ~[apache-cassandra-2.2.4.jar:2.2.4] > at > org.apache.cassandra.streaming.ConnectionHandler$IncomingMessageHandler.run(ConnectionHandler.java:261) > ~[apache-cassandra-2.2.4.jar:2.2.4] > {code} > Because of these, decommission process is not succeeding. > Is interrupting the decommission process safe?
