> HBASE-12422 changed new HTable(Configuration) to not use managed Connections
> anymore
> ------------------------------------------------------------------------------------
>
> Key: HBASE-12835
> URL: https://issues.apache.org/jira/browse/HBASE-12835
> Project: HBase
> Issue Type: Bug
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
> Fix For: 1.0.0, 1.1.0
>
> Attachments: hbase-12835_v1.patch, hbase-12835_v2.patch,
> hbase-12835_v2.patch
>
>
> While debugging something else, I've noticed that HBASE-12422 changed it so
> that new HTable(Configuration, TableName) is not using managed connections
> anymore.
> I thought the plan was to keep new HTable(Conf, TableName) to still use
> managed connections, but allow the new APIs to have un-managed connections.
> With HBASE-12422, there is a big compatibility change for used of the HTable
> interface that suddenly they will be launching connections per HTable
> instance which is a behavioral change and expensive (with all the meta cache,
> zk threads, thread pool, etc). I fear that this will catch unsuspecting users
> by surprise, that is why I think we should revert back to the deprecated
> behavior for 1.0. For master we do not need to make the change, but document
> it.
