Possible deadlock between LeaseManager and FSDirectory
------------------------------------------------------
Key: HDFS-1241
URL: https://issues.apache.org/jira/browse/HDFS-1241
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.20.2, 0.21.0
Reporter: Todd Lipcon
LeaseManager.findPath() locks LeaseManager, then FSDirectory by caling
getFileINode. FSDirectory.unprotectedDelete locks itself and then calls
LeaseManager.removeLeaseWithPrefixPath. This cycle could deadlock.
