Description
TestFileCreation.testFsClose fails to shutdown the MiniDFSCluster on successful exit. Subsequent tests can fail with the following exception:
java.io.IOException: Cannot remove data directory: d:\w\hc7\build\test\data\dfs\data
at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:266)
at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:125)
at org.apache.hadoop.hdfs.TestFileCreation.testDeleteOnExit(TestFileCreation.java:261)
This was seen with JDK7 since testcase execution order is randomized.
