Subject [jira] Commented: (HIVE-30) Hive web interface
Date Fri, 21 Nov 2008 22:21:44 GMT


Joydeep Sen Sarma commented on HIVE-30:

ok - i filed hive-77. i think it makes sense to do any multi-threading cleanup in a separate
jira (since that could be an issue for other server code as well). also we need a good test
suite for this kind of execution environment.

if u can make progress on some of the other issue - i can take a stab at hive-77 in parallel.

regarding the username vs. session: would it be fair to say that passwords are usually on
a per user basis. ie. i am wondering if the flow should be 'specify username/password' and
then 'start new session', 'list sessions' etc. - all within the context of one userid. i am
a little skeptical of the 'set' approach - i think most people will not set anything unless
they have to. for the administrator - it's critical that userid be set - otherwise all load
on the map-reduce cluster and all tables look like they are owned by one user - which is pretty

I understand that this can be easily faked - but at least it sets expectations and sets up
for future ldap etc. integration. Perhaps others can chime in here as well?

> Hive needs a web interface. The initial checkin should have:
> * simple schema browsing
> * query submission
> * query history (similar to MySQL's SHOW PROCESSLIST)
> A suggested feature: the ability to have a query notify the user when it's completed.
> Edward Capriolo has expressed some interest in driving this process.
