Jeremy A. Lucas updated HIVE-3574:
----------------------------------
Description:
Having Hive to submit generated jobs to an M/R cluster via the MapReduce API
would allow for potentially greater compatibility across platforms, in addition
to allowing for these jobs to be run easily against pseudo-clusters in tests
(think MiniMRCluster).
This kind of change could involve something as simple as using a Hadoop
Configuration object with a generic ToolRunner or something similar to run jobs.
Specifically, this kind of change would most likely occur in the execute()
method of org.apache.hadoop.hive.ql.exec.MapRedTask.

already has access to a JobConf object as well, which could serve in itself as
a Configuration object).
