> Remove jdbc stats collection mechanism
> --------------------------------------
>
> Key: HIVE-12164
> URL: https://issues.apache.org/jira/browse/HIVE-12164
> Project: Hive
> Issue Type: Task
> Components: Statistics
> Reporter: Ashutosh Chauhan
> Assignee: Ashutosh Chauhan
> Attachments: HIVE-12164.1.patch, HIVE-12164.2.patch, HIVE-12164.patch

>
> Though there are some deployments using it, usually its painful to setup
> since a valid hive-site.xml is needed on all task nodes (containing
> connection details) and for large tasks (with thousands of tasks) results in
> a scalability issue with all of them hammering DB at nearly same time.
> Because of these pain points alternative stats collection mechanism were
> added. FS stats based system is default for some time.
> We should remove jdbc stats collection mechanism as it needlessly adds
> complexity in TS and FS operators w.r.t key handling.
