DataNode gets stuck while shutting down minicluster
---------------------------------------------------
Key: HDFS-2213
URL: https://issues.apache.org/jira/browse/HDFS-2213
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Fix For: 0.23.0
Attachments: stack.txt
I've seen a couple times where a unit test has timed out. jstacking shows the
cluster is stuck trying to shut down one of the DataNode HTTP servers. The
DataNodeBlockScanner thread also seems to be in a tight loop in its main loop.
