-----------------------------------
This is not causing any issue other than logging an error message. We can print
a single line error message instead of printing the stacktrace.
> 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
> Priority: Major
> Labels: MiniOzoneChaosCluster, Triaged
>
> 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.
