Hive should start moving to the new hadoop mapreduce api.

[yongqiang he]

Hi all,

In offline discussions when we fixing HIVE-1492, we think it maybe
good now to start thinking to move Hive to use new MapReduce context
API, and also start deprecating Hadoop-0.17.0 support in Hive.
Basically the new MapReduce API gives Hive more control at runtime.

Any thoughts on this?


Thanks
