add progress in join and groupby
--------------------------------
Key: HIVE-1305
URL: https://issues.apache.org/jira/browse/HIVE-1305
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Reporter: Namit Jain
Assignee: Paul Yang
Fix For: 0.6.0
The operators join and groupby can consume a lot of rows before producing any
output.
All operators which do not have a output for every input should report progress
periodically.
Currently, it is only being done for ScriptOperator and FilterOperator.
