> I was running the usual Bigtop testing on 2.1.1-beta RC1 with the following
> configuration: 4 nodes fully distributed cluster with security on.
> All of a sudden my DN ate up all of the space in /var/log logging the
> following message repeatedly:
> {noformat}

> in the dataset
> {noformat}
> It wouldn't answer to a jstack and jstack -F ended up being useless.
> Here's what I was able to find in the NameNode logs regarding this block ID:

> This seems to suggest that the block was successfully deleted, but then DN
> got into a death spiral inside of a scanner.
> 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.
