TraceBuilder unable to generate the traces while giving the job history path by globing.
----------------------------------------------------------------------------------------
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.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.
