Subject [jira] Created: (HIVE-335) External Tables should have the option to be marked Read Only

External Tables should have the option to be marked Read Only
-------------------------------------------------------------

                 Key: HIVE-335
                 URL: https://issues.apache.org/jira/browse/HIVE-335
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Metastore, Query Processor
            Reporter: Richard Lee


When creating an External Table, it'd be awesome to have the option of NOT allowing writes
to it (disallow any INSERTs or if hive ever allows UPDATEs).  Adding and Dropping Partitions
should still be allowed.

This will enable hive to "play well" with external data stores other than hdfs where data
should be non-maleable.

I'd recomend the following syntax, which applies ONLY to external tables:

CREATE EXTERNAL [READONLY] TABLE ...
