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

             Summary: Failure detector should detect and ignore local pauses
                 Key: CASSANDRA-9183
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9183
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Brandon Williams
            Assignee: Brandon Williams


A local node can be paused for many reasons such as GC, and if the pause is long enough when
it recovers it will think all the other nodes are dead until it gossips, causing UAE to be
thrown to clients trying to use it as a coordinator.  Instead, the FD can track the current
time, and if the gap there becomes too large, skip marking the nodes down (reset the FD data
perhaps)
