Subject [jira] [Commented] (HIVE-4086) Cross Database Support for Indexes and Partitions (or all DDL statements)
Date Wed, 27 Feb 2013 21:55:13 GMT


Todd Wilson commented on HIVE-4086:

Hello Jarcec:

Your suggestion for the USE command works when querying hive directly, but I'm using a couple
of ODBC drivers (MapR and HortonWorks) and it looks like this command doesn't work (which
made me think this command wasn't working/supported on Hive :/).  Anyways, this is an ODBC
issue I think.  Thanks again for your help.

Best Regards,

> I'd like to see more cross-database support.  I'm using a Cloudera implementation on
Hive .9.  Currently, you can create new databases, you can create tables and views in those
databases, but you cannot create indexes or partitions on those tables.  Likewise, commands
like show partitions or show indexes will only work on table in the default database.  This
would probably also affect statements like Alter Table and Recover Partitions.  Probably also
something like Create Function, but if you want to keep all functions being created in the
default database that would work.  I would be more interested in full cross-database support
for tables and views to start.  Functions for example could all be created in default.  Thank
