> 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.)
