Subject [jira] [Updated] (HADOOP-7418) support for multiple slashes in the path separator
Date Fri, 08 Jul 2011 03:54:16 GMT

Andrew Look updated HADOOP-7418:
--------------------------------

    Attachment: HADOOP-7418.txt

I think I have the solution here... It seems that if there's only one backslash it doesn't
necessarily get replaced.. do you think my regex for the backslashes is correct?

Thanks for all your help!

> 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
