      Description

      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:

      2013-09-18 20:51:12,046 INFO org.apache.hadoop.hdfs.server.datanode.BlockPoolSliceScanner: BP-1884637155-10.224.158.152-1379524544853:blk_1073742189_1369 is no longer in the dataset
      

      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.
