-----------------------------------------
Fix Version/s: 3.x
> The JMX stats for Speculative Retry stops moving during a node failure outage
> period
> ------------------------------------------------------------------------------------
>
> Key: CASSANDRA-6188
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6188
> Project: Cassandra
> Issue Type: Bug
> Components: Observability
> Environment: One data center of 4 Cassandra-2.0 nodes with default
> configuration parameters deployed on 4 separate machines. A testing app (with
> either Astyanax or DataStax client driver) interacts with the Cassandra data
> center. A traffic generator is sending traffic to the testing app for testing
> purpose.
> Reporter: Li Zou
> Assignee: Ryan McGuire
> Priority: Trivial
> Fix For: 3.x
>
>
> Under normal testing traffic level with default Cassandra Speculative Retry
> configuration for each table (i.e. 99 percentile), JConsole shows that the
> JMX stats for Speculative Retry increments slowly. However, during the node
> failure outage period (i.e. immediately after the node was killed and before
> the gossip figures out that the node is down), JConsole shows that the JMX
> stats for Speculative Retry stops moving. That is, for around 20 seconds, the
> JMX stats for Speculative Retry does not move.
> This is true for all other Speculative Retry options.
