change hive assumption that local mode mappers/reducers always run in same jvm
-------------------------------------------------------------------------------
Key: HIVE-1846
URL: https://issues.apache.org/jira/browse/HIVE-1846
Project: Hive
Issue Type: Bug
Reporter: Joydeep Sen Sarma
Assignee: Joydeep Sen Sarma
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.
