Naming convention for files being moved into HDFS

Hadoop throws an error saying that
-bash-3.2$ hadoop fs -put 20100822_03\:47\:08.txt /testing
put: java.net.URISyntaxException: Relative path in absolute URI: 20100822_03:47:08.txt
Usage: java FsShell [-put <localsrc> ... <dst>]

This happens whenever there is a colon in the name of the file. Here the colon is flanking by a backslash making it a literal but hadoop still throws the error. If the colons are removed then the error does not crop up. So it must be some issue with handling the URI.

DO let me know if there is any other information that you need. I would be glad to provide it. Thank you.

The hadoop version is Hadoop 0.20.2+320
