Ranjit Mathew commented on MAPREDUCE-2078:
------------------------------------------
Some minor comments:
* In ??If the input is a file then its directly?? in the comment to
{{processInput()}}, change "its" to "it's" or "it is".
* Just use plain old JavaDoc style comments for {{processInput()}}.
* In {{processInput()}}, you can now directly use the {{FileStatus}} object
{{inStatus}} instead of calling {{fs.getFileStatus()}} again.

> I was trying to generate the traces for MR job histories by using
> TraceBuilder. However, it's unable to generate the traces while giving the
> job history path by globing. It throws a file not found exception even though
> the job history path is exists.
> I have provide the job history path in the below way.
> hdfs://<<clustername>>/dir1/dir2/dir3/*/*/*/*/*/*/
> Exception:
> java.io.FileNotFoundException: File does not exist:
> hdfs://<<clustername>>/dir1/dir2/dir3/*/*/*/*/*/*
