It seems that you have started hive in one terminal, and in another you are trying spark+hive. This is the reason you are facing this issue. Kindly do not start hive shell.
And, to start spark shell follow below command.
bin/spark-shell --jars /home/<path_to>/hive/lib/*.jar --driver-class-path /home/.../hive/lib/*.jar
