Subject [jira] [Commented] (MAPREDUCE-6271) org.apache.hadoop.mapreduce.Cluster GetJob() display warn log
Date Mon, 23 Mar 2015 14:33:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14375968#comment-14375968
] 

Peng Zhang commented on MAPREDUCE-6271:
---------------------------------------

Thanks [~jira.shegalov] & [~zxu] for your explanation.
As Gera's suggestion, I updated patch to JobConf(false) to remove "attempt to override final
parameter" warn log.

> When using getJob() with MapReduce 2.7, warn log caused by configuration loaded twice
is displayed every time. And when job completed, this function will display warn log of "java.io.FileNotFoundException"
> And I think this is related with MAPREDUCE-5875, the change in GetJob() seems to be not
needed, cause it's only for test.
