Subject [jira] [Commented] (MAPREDUCE-5215) mapreduce.Job is missing getJobClient() so its incompatible with MR1
Date Thu, 14 Nov 2013 06:39:25 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13822216#comment-13822216

Robert Kanter commented on MAPREDUCE-5215:
------------------------------------------

I agree, the method was marked as package private, so we made no guarantees about its availability.
 We don't want to set a precedent for this.

> The method {{org.apache.hadoop.mapred.JobClient getJobClient()}} is in MR1's {{mapreduce.Job}}
but doesn't exist in MR2's, which makes them incompatible.  MR2's implementation of {{Job}}
doesn't use a JobClient object, but we can create one and return it.
