Supratim Deka created HDDS-1765:
-----------------------------------
Summary: destroyPipeline scheduled from finalizeAndDestroyPipeline
fails for short dead node interval
Key: HDDS-1765
URL: https://issues.apache.org/jira/browse/HDDS-1765
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: SCM
Reporter: Supratim Deka
This happens when
OZONE_SCM_PIPELINE_DESTROY_TIMEOUT exceeds the value of
OZONE_SCM_DEADNODE_INTERVAL. This is the case for start-chaos.sh
When a Datanode is shutdown, SCM Stale node handler calls
finalizeAndDestroyPipeline() which schedules destroyPipeline() operation with a
delay
of OZONE_SCM_PIPELINE_DESTROY_TIMEOUT. By the time this gets scheduled, dead
node handler would have destroyed the pipeline.
