Gourab Taparia commented on PHOENIX-6838:
-----------------------------------------
Thanks [~stoty] for linking and fixing.
Agree with you, we can have the client side also analysed and improved - we can
keep this item open for that piece. I can take a look at that as part of this.
> Review unpooled HConnection usage
> ---------------------------------
>
> Key: PHOENIX-6838
> URL: https://issues.apache.org/jira/browse/PHOENIX-6838
> Project: Phoenix
> Issue Type: Task
> Components: core
> Reporter: Istvan Toth
> Assignee: Gourab Taparia
> Priority: Major
>
> Directly creating HConnections puts load on ZK and Kerberos.
> We ususally sidestep this problem by creating a PhoenixConnection, which
> re-uses the HConnection object from the appropriate CQSI singleton.
> Review the places where create unpooled HConnections, and switch to pooled
> PhoenixConnections where it makes sense.
