Bennie Schut commented on HIVE-1846:
------------------------------------
One of the problems I ran into on local mode was a missing plan. If this is
solved perhaps it also solves part of HIVE-1675.
> change hive assumption that local mode mappers/reducers always run in same
> jvm

> we are trying out a version of hadoop local mode that runs multiple
> mappers/reducers by spawning jvm's for them. In this mode hive mappers fail
> in reading the plan file. it seems that we assume (in the setMapredWork call)
> that local mode mappers/reducers will run in the same jvm (we can cache the
> current plan in a global var and don't serialize to a path). this needs to
> get fixed.
