Junping Du commented on HDFS-5225:
----------------------------------
Hi [~ozawa], thanks for the patch! Besides fixing test failures, it would be
nice if you can attach log of your reproduce bug (only related part) so that
Roman can judge if it is the same bug.
> datanode keeps logging the same 'is no longer in the dataset' message over
> and over again

> I was running the usual Bigtop testing on 2.1.1-beta RC1 with the following

> I can keep the cluster running for a few days if anybody is willing to take a
> look. Ask me for creds via a personal email.
