> Add Hadoop-based DBCPConnectionPool
> -----------------------------------
>
> Key: NIFI-7257
> URL: https://issues.apache.org/jira/browse/NIFI-7257
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Priority: Major
> Fix For: 1.12.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> Although our DBCPConnectionPool has options for doing Kerberos
> authentication, drivers that under the covers rely on Hadoop's
> UserGroupInformation won't see the logged in user from our service. It would
> be helpful if we had a service similar to DBCPConnectionPool, but with
> hadoop-common on the classpath so that we can handle the the UGI related
> stuff.
> This new service would be similar to a combination of DBCPConnectionPool and
> some of the stuff done in Hive3ConnectionPool, but we would not bundle any
> Hadoop dependency, and instead the user must specify hadoop-common as part of
> the driver dependencies, or a shaded jar that includes it (as phoenix does).
