> Subject: Hive accessing metastore
> Hi team,
> What we have observed is, hive creates so many connections to metastore (mysql). This makes us change the numer of connections to mysql. Specifically 2 connections per user out of which one remains idle and other one is used. When we talk about using hive prompt for jobs.
> Can anyone explain me how does hive manages its connections to metastore database.
> Also why 2 connections ? Can we pool connections from hive to metastore by setting any variable ?
> is it one for every Job submitted by every user ? if not then how and when hive makes connections to metastore.
> 2. Is it possible to limit the number of maximum connections hive could make to mysql metastore ? Or is it possible to limit number of maximum jobs than can be submitted to hive at anytime ?
> Please help
> Thanks in advance.
> Cheers !!!
