> In HBaseResources.scala :
> {code}
> case class RegionResource(relation: HBaseRelation) extends ReferencedResource {
>   var connection: Connection = _
>   var rl: RegionLocator = _
> ...
>   override def init(): Unit = {
>     connection = ConnectionFactory.createConnection(relation.hbaseConf)
> {code}
> Connection is created per RegionResource.
> This is not necessary.
> Caching of Connection's should be provided to reduce the number of concurrent Connection's.
