--------------------------------------------

             Summary: Decommissioned nodes can remain in gossip
                 Key: CASSANDRA-10371
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10371
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Brandon Williams
            Priority: Minor


This may apply to other dead states as well.  Dead states should be expired 
after 3 days.  In the case of decom we attach a timestamp to let the other 
nodes when it should be expired.  It has been observed that sometimes a subset 
of nodes in the cluster never expire the state, and through heap analysis of 
these nodes it is revealed that the epstate.isAlive check returns true when it 
should return false, which would allow the state to be evicted.  This may have 
been affected by CASSANDRA-8336.
