Review request for hive.
Bugs: HIVE-4144
https://issues.apache.org/jira/browse/HIVE-4144
Repository: hive-git
Description
-------
A recent hive-user mailing list conversation asked about having a command to
show the current database.
http://mail-archives.apache.org/mod_mbox/hive-user/201303.mbox/%3CCAMGr+0i+CRY69m3id=DxthmUCWLf0NxpKMCtROb=uauh2va...@mail.gmail.com%3E
MySQL seems to have a command to do so:
{code}
select database();
{code}
http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_database
We should look into having something similar in Hive.
