             Summary: Introduce immutable-table table property and if set, 
disallow insert-into
                 Key: HIVE-6406
                 URL: https://issues.apache.org/jira/browse/HIVE-6406
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sushanth Sowmyan
            Assignee: Sushanth Sowmyan


As part of HIVE-6405's attempt to make HCatalog and Hive behave in similar ways 
with regards to immutable tables, this is a companion task to introduce the 
notion of an immutable table, wherein all tables are not immutable by default, 
and have this be a table property. If this property is set for a table, and we 
attempt to write to a table that already has data (or a partition), disallow 
"INSERT INTO" into it from hive. This property being set will allow hive to 
mimic HCatalog's current immutable-table property.
