MiniDFSCluster exists a race condition that lead to data node resources are not
properly released
-------------------------------------------------------------------------------------------------
Key: HADOOP-1063
URL: https://issues.apache.org/jira/browse/HADOOP-1063
Project: Hadoop
Issue Type: Bug
Components: test
Affects Versions: 0.12.0
Reporter: Hairong Kuang
Assigned To: Hairong Kuang
Fix For: 0.13.0
In MiniDFSCluster, there is a possibility that a data node gets shutted down
before it is constructed. This leads to the situation that the data node's
resources are not properly released. In Cygwin I observe that the data node
directory is still kept locked after a miniDFSCluster is shut down.
