chen xiao commented on HIVE-335:
--------------------------------

I believe it's a very useful feature. Since no one want to take this task, is there any work
round for it?

>             Project: Hive
>          Issue Type: Improvement

> 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 ...
