Subject [jira] [Commented] (MAPREDUCE-5618) Make applicationType pluggable
Date Mon, 11 Nov 2013 09:02:17 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13818782#comment-13818782
] 

Karthik Kambatla commented on MAPREDUCE-5618:
---------------------------------------------

Looking at the source, this would affect the behavior of Cluster, CLI getJobs/getAllJobs methods.
These methods won't return MR jobs started Oozie, Pig, or Hive. This would be an incompatible
change.

> MR AM sets the applicationType to be "MAPREDUCE". Downstream projects like Pig, Hive,
Oozie might want to set this to a different value for their error-handling, query-tracking
etc. Making this pluggable should help this cause.
