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.
