-------------------------------------
Great, thanks Aaron!
I'm running OS X Snow Leopard so that may be causing problems on my end... I've
heard of others having trouble building the C++ libraries in HDFS (see
http://cxwangyi.blogspot.com/2010_04_01_archive.html ) and apparently some mods
need to be made to get things to run correctly.
Have you heard of any such issues on OS X?

> the parsing of the input path string to identify the uri authority conflicts
> with the file system paths. For instance the following is a valid path in
> both the linux file system and the hdfs.
> //user/directory1//directory2.
> While this works perfectly fine in the command line for manipulating hdfs,
> the same fails when specified as the input path for a mapper class with the
> following expcetion.
> Exception in thread "main" java.net.UnknownHostException: unknown host: user
> at org.apache.hadoop.ipc.Client$Connection.<init>(Client.java:195)
> as the org.apache.hadoop.fs.Path class assumes the string that follows the
> '//' to be an uri authority
