Subject [jira] [Created] (HADOOP-9681) FileUtil.unTarUsingJava() should close the InputStream upon finishing
Date Mon, 01 Jul 2013 18:54:20 GMT
Chuan Liu created HADOOP-9681:

             Summary: FileUtil.unTarUsingJava() should close the InputStream upon finishing
                 Key: HADOOP-9681
                 URL: https://issues.apache.org/jira/browse/HADOOP-9681
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 3.0.0, 2.1.0-beta
            Reporter: Chuan Liu
            Assignee: Chuan Liu
            Priority: Minor

In {{FileUtil.unTarUsingJava()}} method, we did not close input steams explicitly upon finish.
This could lead to a file handle leak on Windows.

I discovered this when investigating the unit test case failure of {{TestFSDownload.testDownloadArchive()}}.
FSDownload class will use {{FileUtil.unTarUsingJava()}} to unpack some temporary archive file.
Later, the temporary file should be deleted. Because of the file handle leak, the {{File.delete()}}
method fails. The test case then fails because it assert the temporary file should not exist.
