Subject [jira] Commented: (HADOOP-6539) Hadoop 20 Doc Backport
Date Wed, 17 Feb 2010 03:40:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12834627#action_12834627
] 

Amareshwari Sriramadasu commented on HADOOP-6539:
-------------------------------------------------

I looked at mapred-tutorial and streaming docs.

In mapred-tutorial.xml,
         " In Streaming, the files can be distributed through command line
           options <code>-files</code> and <code>-archives</code>.</p>"
This change does not look correct. -files and -archives are not streaming options. They are
generic options. I think above line can be deleted from mapred_tutorial.xml. We can add a
line in "Large files and archives in Hadoop Streaming" section in streaming.xml saying "To
be backward compatible, streaming also supports -cacheFile and -cacheArchive options for distributing
large files and archives".

In streaming.xml, many changes ported from trunk do not apply to 0.20. Trunk has more changes
like MAPREDUCE-849 (which changed configuration names) and MAPREDUCE-787 (which has undone
the documentation changes in MAPREDUCE-813). We need to backport changes only from MAPREDUCE-813
and HADOOP-5592 for streaming doc.
