                 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/*/*/*/*/*/*
        at org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:525)
        at org.apache.hadoop.tools.rumen.TraceBuilder$MyOptions.<init>(TraceBuilder.java:88)
        at org.apache.hadoop.tools.rumen.TraceBuilder.run(TraceBuilder.java:183)
        at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)

        at org.apache.hadoop.tools.rumen.TraceBuilder.main(TraceBuilder.java:121)

It's truncating the last  slash in the path.
