[Help] How to create a new table when automatically generating schema?

[Jiajun Xie]

Hello~
  I need to create a new table in the metastore.

  I tried to update `metastore/src/model/package.jdo` and
`metastore/scripts/upgrade/derby/hive-schema-1.2.0.derby.sql`. (My feature
is based on branch-1.2)
  Then I set
`datanucleus.schema.autoCreateTables`,
`datanucleus.schema.generateDatabase.createScript`.
None of them work.

How to create a new table when automatically generating schema? Thank you
very much.
