Jakob Homan updated HIVE-2233:
------------------------------
Attachment: HIVE-2233.patch
Patch for review.
* Add new option {{hive.cli.print.current.db}} that, if enabled, will show the
currently selected database in the prompt like so:
{noformat}Hive history
file=/tmp/jhoman/hive_job_log_jhoman_201108091406_1596091783.txt
hive (default)> show
> tables;
OK
Time taken: 3.07 seconds
hive (default)> use abcdefghijklmnopqrstuvwxyz;
OK
Time taken: 0.013 seconds
hive (abcdefghijklmnopqrstuvwxyz)> show
> tables;
OK
Time taken: 0.095 seconds
hive (abcdefghijklmnopqrstuvwxyz)> set hive.cli.print.current.db=false;
hive>{noformat}
The current database is obtained by creating a Hive instance within the
CliSessionState. This appears to be a reasonable solution, though an
alternative would be to add a get_current_db call to the Thrift interface and
go through the already existing HiveClient in the CliSessionState.
Since this only affects interactive clients, TestCliDriver tests aren't
applicable. It's been tested manually (as above), and I'd be happy to write
some unit tests, but I've already got two patches that add Mockito waiting to
be committed (HIVE-2334 and HIVE-2171), so there's not much point in adding it
again.
