QueryPlan.outputs should be determined at compile time
------------------------------------------------------
Key: HIVE-1159
URL: https://issues.apache.org/jira/browse/HIVE-1159
Project: Hadoop Hive
Issue Type: Improvement
Affects Versions: 0.6.0
Reporter: Zheng Shao
Assignee: Zheng Shao
Currently, we change QueryPlan.outputs at execution time of DDLTask, MoveTask.
The post execution hook relies on QueryPlan.outputs to log the changed entities.
This makes the serialization hard, because we need to serialize the outputs
when each of the Tasks are done. This is even harder given that we allow
parallel execution of tasks now.
We should be able to determine all that at compile time.
