[Hive-user] HIVE Server multiple instances

[Hive-user] HIVE Server multiple instances

Hello,

I have one instance of HIVE JDBC server running on port 10000. Can I run another
instance on different port ? Would it cause a concurrency issue on the
underlying data warehouse files ? Please clarify.

Thanks,
V.Senthil Kumar

Matthew Rathbone: Why would you want to run two? I think it is multithreaded, so you can query it from two different connections -- Matthew Rathbone Foursquare | Software Engineer | Server Engineering Team matthew@foursquare.com | @rathboma | 4sq On Monday, May 2, 2011 at 6:41 PM, V.Senthil Kumar wrote: Hello,
V.Senthil Kumar: Thanks Matthew. The wiki page http://wiki.apache.org/hadoop/Hive/HiveServer says its single threaded. I have a queue of queries which gets added dynamically all the time. By the time I run 1 query using 1 JDBC connection, the queue gets added more queries and builds up a backlog. So, I was that's why I was wondering whether I can run two or more instances to avoid having a big backlog in queue. ----- Original Message ---- From: Matthew Rathbone To: user@hive.apache.org Sent: Tue, May 3, 2011
Matthew Rathbone: Even if it is single threaded it certainly seems to support multiple connections. We run 5 workers all connected at the same time executing a different query each ( with a different connection per worker).
