-------------------------------
Summary: TestGlobPaths should re-use the MiniDFSCluster to avoid
failure on Windows
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
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
