[jira] [Commented] (TEZ-637) [MR Support] Add all required info into JobConf for MR related I/O/P

["Bikas Saha (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TEZ-637?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13899659#comment-13899659 ] 

Bikas Saha commented on TEZ-637:
--------------------------------

mapred.jar	String	job.jar location in job directory
map.input.file	 String	 The filename that the map is reading from
map.input.start	 long	 The offset of the start of the map input split
map.input.length	long	The number of bytes in the map input split

The above would be hard to set at runtime unless they have been set at the client. Other than that the rest are already being set or being added in this patch.
