Thanks Uma!  I didn't think I had privs to move, but I learned I can move it myself.

Updated patch to add the tests that I forgot to svn add.

> Performing an hdfs -get on a file, modifying the file, and using hdfs -put to place the file back into HDFS results in a checksum error.  It seems that the problem is a .crc file being generated locally from the -get command even though the -crc option was NOT specified.
