> URL: https://issues.apache.org/jira/browse/HDFS-2444
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 0.21.0, 0.23.0
> Reporter: Hou Song
> Attachments: HDFS-2444.patch

>
> 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.
