Matt Pollock commented on HIVE-335:
-----------------------------------
My organization has lots of data producing users/accounts and not all data
producers are hive users. It would be extremely valuable to be able to create a
read-only external table to avoid data copy and enable flexible query on data
the consumer did not produce but has read access to.
> External Tables should have the option to be marked Read Only

> 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 ...
