Description

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.util.ToolRunner.run(ToolRunner.java:79)
at org.apache.hadoop.tools.rumen.TraceBuilder.main(TraceBuilder.java:121)

It's truncating the last slash in the path.
