Subject decommissioned node still in "LoadMap" in JMX Management Console
Date Wed, 09 Nov 2011 07:28:41 GMT
Hi,

on our production cluster of 8 nodes which is running cassandra 0.8.7
we still see in the MBean
"org.apache.cassandra.db:type=StorageService.LoadMap" in JMX
Management console the 9th node we added for testing for a short time.
After the testing we decommissioned the 9th node and has been
reinstalled for another use. The node is not reported by `nodetool
ring` not is it in
"org.apache.cassandra.db:type=StorageService.LiveNodes" MBean.

Is it a feature or a bug?

10.2.54.85 is the 9th node.
