Joydeep Sen Sarma commented on HIVE-30:
---------------------------------------
@Edward - the thrift Hive Server is implemented in Java - all that C++ code is
generated thrift code for the client side stubs in all likelihood.
@ashish - from what i see - the thrift hiveserver does not manage sessions
right now. I think at this point we are all in agreement and perhaps we should
spec out what the hive session manager common to all access paths does:
- start/stop session
- validate user credentials and maintain stats/logs per user/session
- compile queries
- submit any map-reduce jobs
submitting a map-reduce task by itself is low overhead - and also desirable in
the session manager (so that an admin can come to the session manager and see
and kill running map-reduce jobs). however - beyond this - any actual reading
of the data files ought to definitely occur in the client (ie. cli/jdbc
server/hwi).
given that the thrift server does not manage sessions right now - and the
current patch has the beginnings of a session manager - we could as well begin
here by teasing apart the generic session management code/server and then
starting to adapt other clients to it ..

> Key: HIVE-30
> URL: https://issues.apache.org/jira/browse/HIVE-30
> Project: Hadoop Hive
> Issue Type: Bug
> Reporter: Jeff Hammerbacher
> Assignee: Edward Capriolo
> Priority: Minor
> Attachments: HIVE-30.patch
>
>
> 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.
