[jira] [Commented] (HADOOP-9529) It looks like hadoop.tmp.dir is being used both for local and hdfs directories

    [ https://issues.apache.org/jira/browse/HADOOP-9529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13645875#comment-13645875 ] 

Arpit Gupta commented on HADOOP-9529:
-------------------------------------

I noticed that mapred.system.dir and staging dir use hadoop.tmp.dir in the defaults thus it ends up being used for both local file system and hdfs.

> I would like to separate out the files that are written to /tmp so I added a definition for hadoop.tmp.dir which value I understand as a local folder. It apparently also specifies an HDFS folder.
