Florin Diaconeasa commented on HIVE-80:
---------------------------------------
Hello,
I'm thinking about writing a Hive client in order to handle some of the queries
that i wish to run and the dependencies between them.
>From what i read on the Hive wiki (
>http://wiki.apache.org/hadoop/Hive/HiveServer ) it appears that the hive
>server is single threaded.
I might be mistaking, but this is what i understand from that text: if i launch
2 requests from my client towards the hive server, the hive server will not
handle them in parallel and the hadoop requests done by hive itself will run
one after another, not in parallel.
Is this right? If (hopefully) not :) , could someone please clarify that for
me, if possible?
Thank you.
