[jira] [Commented] (MAPREDUCE-6506) Make the reducer-preemption configs consistent in how they handle defaults

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15521521#comment-15521521 ] 

Haibo Chen commented on MAPREDUCE-6506:
---------------------------------------

[~kasha] In what ways do you see the defaults are handled differently. I can only see the default of COMPLETED_MAPS_FOR_REDUCE_SLOWSTART is declared in RMContainerAllocator.java, rather than MRJobConfig as others. Do you mean we need to move the default to MRJobConfig?
