[jira] [Created] (MAPREDUCE-7125) JobResourceUploader creates LocalFileSystem when it's not necessary

Peter Cseh created MAPREDUCE-7125:
-------------------------------------

             Summary: JobResourceUploader creates LocalFileSystem when it's not necessary 
                 Key: MAPREDUCE-7125
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7125
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: job submission
            Reporter: Peter Cseh


When the property {{mapreduce.job.log4j-properties-file}} is set a local filesystem is created even if it's never used:
https://github.com/apache/hadoop/blob/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/JobResourceUploader.java#L858-L866

The localFS should only be created when required.
