Description

HADOOP-4679 applies to 0.18.3 only. I'm able to consistently reproduce the same issue in 0.19.0.

For reference, our Datanodes use 4 independent drives. When we pull any of them, the Datanode begins logging hundreds of the following message per second:

2008-12-31 03:33:48,627 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: Waiting for threadgroup to exit, active threads is 2
