Description

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
