allow more tables in union all
-------------------------------
Key: HIVE-971
URL: https://issues.apache.org/jira/browse/HIVE-971
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Reporter: Hao Liu
We used to union more than 128 tables in hive, which did not work. But it is a
useful feature to support query aggregating multi fct tables.
(not sue if it is fixed already, pls. close the task if it is not true any
longer)
