------------------------------------
Summary: Avoid frequent pipeline close action from DN
Key: HDDS-13618
URL: https://issues.apache.org/jira/browse/HDDS-13618
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Sumit Agrawal
When DN ratis identify issues over pipeline, it trigger close pipeline action,
below are few cases:
# When follower is slow
# When leader is not elected and remain in candidate for longer duration
# Any other issue in pipeline like disk out of space trigger failure
This keeps triggering close pipeline action, even though close actions are
queued in DN command queue. And if there is any issue for DN pipeline closure,
it can result in huge such action every HB.
Already there is an optimization that within one HB, it will avoid duplicate
pipeline close action.
So this repeatative trigger can be avoided by checking the command queue.
