> Currently HCat allow a selected set of DDL statements and delegate them to
> Hive. We shall allow more DDL statements. The criteria is the DDL statement
> is nonblocking. Locking is not considered since otherwise most DDL operation
> will be blocking. Allowed DDL includes:
> * database DDL
> * view DDL
> * index DDL (no actual index building, eg, alter index rebuild is excluded)
> * authorization DDL
> * lock management DDL
> * table management DDL (no create as select)
> * table partition management DDL (no CONCATENATE, archive/unarchive)
> * table schema management DDL
> * Misc: show function, explain, dfs, set
> import/export which are supported before is dropped since they are blocking.
