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.
> Make applicationType pluggable

> Key: MAPREDUCE-5618
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5618
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mr-am
> Affects Versions: 2.2.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla

> 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.
