[jira] [Created] (HDFS-2444) A bug in unit test: TestDFSShell.testText()

A bug in unit test: TestDFSShell.testText()
-------------------------------------------

                 Key: HDFS-2444
                 URL: https://issues.apache.org/jira/browse/HDFS-2444
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: test
    Affects Versions: 0.21.0
            Reporter: Hou Song


testText() writes the same random String into a ByteArray in memory and a GZIPOutputStream in DFS. After closing GZIPOutputStream, it reads it back using shell command -text, and compares it against the ByteArray. However, before comparing, the shell output and the ByteArray are both reset, making the comparison useless. 
What's more, after closing the GZIPOutputStream, DFS is unable to find the file, and the -text command failed to read, giving no output.
