Does anyone know if insert into statement is supposed to work across
databases/schemas?

For instance if I do this the target table gets appended correctly:

insert into table target select * from source;

However, if I have another target table in a different database, the
target table simply gets overwritten instead of appended:

insert into table my_database.target select * from source;

To get around this, one needs to switch to the target database first,
then run the insert into statement like this:

insert into table target select * from default.source;

Just wanna confirm if this is a bug.  Thx.

I haven't used insert into but i observed a similar problem earlier-
https://issues.apache.org/jira/browse/HIVE-2617

You can check against the trunk or open a jira.

This query works on my hive 0.8

insert into table tmp.testtest select user,city from source;

Did you run the insert into query twice?  And did it append?

>From what I observred the query will complete successfully, but it
overwrites instead of append.  That's the problem.

Yes, same problem here, sorry I missed your point and tested only once.
