["James Carman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5420?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13725191#comment-13725191 ] 

James Carman commented on MAPREDUCE-5420:
-----------------------------------------

I was going to tackle this one.  I am removing all references to that string from the code except for the mention in DeprecatedProperties.apt.vm.  However, there's one test case that mentions it in its comments, but I believe it's misleading:

{code}
  /**
   * Tests task's temp directory.
   * 
   * In this test, we give different values to mapreduce.task.tmp.dir
   * both relative and absolute. And check whether the temp directory 
   * is created. We also check whether java.io.tmpdir value is same as 
   * the directory specified. We create a temp file and check if is is 
   * created in the directory specified.
   */
  @Test
  public void testTaskTempDir(){
  ...
  }
{code}

> mapreduce.task.tmp.dir no longer has any effect, so it should no longer be documented in mapred-default.  (There is no YARN equivalent for the property.  It now is just always ./tmp).
