             Summary: TestNamenodeRetryCache fails on Windows due to incorrect cleanup
                 Key: HDFS-5100
                 URL: https://issues.apache.org/jira/browse/HDFS-5100
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 3.0.0, 2.3.0
            Reporter: Chuan Liu
            Assignee: Chuan Liu
            Priority: Minor


The test case fails on Windows with the following exceptions.

{noformat}
java.io.IOException: Could not fully delete C:\hdc\hadoop-hdfs-project\hadoop-hdfs\target\test\data\dfs\name1
	at org.apache.hadoop.hdfs.MiniDFSCluster.createNameNodesAndSetConf(MiniDFSCluster.java:759)
	at org.apache.hadoop.hdfs.MiniDFSCluster.initMiniDFSCluster(MiniDFSCluster.java:644)
	at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:334)
	at org.apache.hadoop.hdfs.MiniDFSCluster$Builder.build(MiniDFSCluster.java:316)

	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...
{noformat}

The root cause is that the {{cleanup()}} only try to delete root directory instead of shutting down the MiniDFSCluster. Every test case in this unit test will create a new MiniDFSCluster during {{setup()}} step. Without shutting down the previous cluster, the new cluster creation will fail with the above exception due to blocking file handling on Windows.
