Subject [jira] [Commented] (MAPREDUCE-5156) Hadoop-examples-1.x.x.jar cannot run on Yarn
Date Wed, 22 May 2013 07:03:25 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13663874#comment-13663874
] 

Hudson commented on MAPREDUCE-5156:
-----------------------------------

Integrated in Hadoop-trunk-Commit #3774 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/3774/])
    MAPREDUCE-5156. Change hadoop examples ProgramDriver to be able to run 1.x examples jar
on top of YARN. This change breaks 0.23.x direct usages of ProgramDriver. Contributed by Zhijie
Shen. (Revision 1485085)

     Result = SUCCESS

> M/R examples are run through ProgramDriver.driver. ProgramDriver.driver returns void
in hadoop-1, while it returns int in hadoop-2. Therefore, the function signatures in the example
jar and yarn are incompatible.
