supratimdeka opened a new pull request #1019: HDDS-1603. Handle Ratis Append Failure in Container State Machine. Contributed by Supratim Deka
URL: https://github.com/apache/hadoop/pull/1019
 
 
   https://issues.apache.org/jira/browse/HDDS-1603
   
   The scope of this jira is to build on https://issues.apache.org/jira/browse/RATIS-573
   and define the handling for Ratis log append failure in Ozone Container State Machine.
   1. Enqueue pipeline unhealthy action to SCM, add a reason code to the message.
   2. Trigger immediate heartbeat to SCM
   
   Ratis-573 is not available in trunk. So this patch starts with an entry point in XceiverServerRatis which will be hooked up to notifyLogFailed() callback defined in StateMachine as part of RATIS-573.
   
   Notify Ratis volume unhealthy to the Datanode is not implemented in this patch
