> 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.
