> --------------------------------------------------------------------------

> Key: HDFS-5093
> URL: https://issues.apache.org/jira/browse/HDFS-5093
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0, 2.3.0
> Reporter: Chuan Liu
> Assignee: Chuan Liu
> Priority: Minor
> Attachments: HDFS-5093.1.patch, HDFS-5093.patch

>
> Some test cases in TestGlobPaths fail on Windows because they try to create a
> new MiniDFSCluster though there is already one created at {{setUp()}}. This
> leads to failure on Windows because the new cluster will try to clean the old
> name node file that was opened by the existing cluster -- on Windows, the
> process or thread cannot delete the file opened in normal Java APIs by
> another process or thread.
> An example failure run looks like the following.
> {noformat}
> testGlobWithSymlinksOnFS(org.apache.hadoop.fs.TestGlobPaths) Time elapsed:
> 47 sec <<< ERROR!
> java.io.IOException: Could not fully delete
