> After upgrading to CDH 5.9.1/Phoenix 4.10/Spark 1.6 from CDH 5.5.2/Phoenix 4.6/Spark 1.5, streaming jobs that read data from Phoenix no longer release their zookeeper connections, meaning that the number of connections from the driver grow with each batch until the ZooKeeper limit on connections per IP address is reached, at which point the Spark streaming job can no longer read data from Phoenix.
