> 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=uauH2vAHng@mail.gmail.com%3E
> MySQL seems to have a command to do so:

> We should look into having something similar in Hive.
