      Description

      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.
