             Summary: Catch read repair timeouts and add metrics to indicate they occurred
                 Key: CASSANDRA-16880
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16880
             Project: Cassandra
          Issue Type: Improvement
          Components: Observability/Metrics
            Reporter: Josh McKenzie
            Assignee: Josh McKenzie


When we fire off async read repairs onto their own executor they may time out and in doing so, we don't have anything that stops them from propagating that timeout exception the way up to CassandraDaemon's uncaught exception handler. When this happens we logs at ERROR.

Obviously a timeout isn't great, but it's not an ERROR, so we should trap them instead and add some metrics around this occurrance.
