> It would be a great to have a tool, running on a real grid, to perform function test
(and stress tests to certain extent) for the file operations. The tool would be written in
Java and makes HDFS API calls to read, write, append, hflush hadoop files. The tool would
be usable standalone, or as a building block for other regression or stress test suites (written
in shell, perl, python, etc).
