John Sichi commented on HIVE-1517:
----------------------------------
This case needs to work:
{noformat}
use db1;
create table t(...);
create view v as select * from t;
use db2;
select * from db1.v;
{noformat}
What this means is that when we store the definition of v, we need to store a
fully-qualified db1.t reference. Otherwise, when we expand the view in the
later query, we'll look for t in db2 (incorrect) rather than db1 (correct).
