-----------------------------------
Key: HCATALOG-261
URL: https://issues.apache.org/jira/browse/HCATALOG-261
Project: HCatalog
Issue Type: New Feature
Reporter: Daniel Dai
Assignee: Daniel Dai
Fix For: 0.4
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.
