> 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/*/*/*/*/*/*
