Key: MAPREDUCE-2078
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2078
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tools/rumen
Reporter: Vinay Kumar Thota
Assignee: Amar Kamat
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/*/*/*/*/*/*

It's truncating the last slash in the path.
