>            Reporter: Amin Abbaspour
>            Assignee: Amin Abbaspour
>            Priority: Minor
>              Labels: easyfix, patch, performance, pull-request-available, security

> WebHCat launches new hcat scripts for each DDL call which makes it unsuitable for interactive
REST environments.
> This change to speed up /ddl query calls by running them over JDBC connection to Hive
thrift server.
> Also being JDBC connection, this is secure and compatible with all access policies define
in Hive server2. User does not have metadata visibility over other databases (which is the
case in hcat mode.)
