Thanks @ayushtkn.
> Just to know, does the Jenkins also complains about this?
Yes, Jenkins does report this e.g
https://ci-hadoop.apache.org/job/hadoop-multibranch/job/PR-3359/4/artifact/out/patch-unit-hadoop-hdfs-project_hadoop-hdfs.txt
And I also tried to repro on Mac only. It was reproduced one time with
single test run (debug mode) but simple rerun is always failing with the same
issue.
> Again just asking is there a test-only fix possible, without going to Prod
files,
Sure thing, would be happy to fix this by tests only but given how replicas
are built up by BlockPoolSlice instance after Datanode is restarted, I think it
might be tough to achieve it. At the same time, I am trying to keep source code
changes as clear with descriptions as possible to ensure devs understand that a
particular flag is for test use only.
FYI @LeonGao91, if you could also review, it would be great. Thanks
