You have not entered your Spark master URL correctly. It could be because upper case error. Please use this command to ensure the path to hibench.spark.masterin the file conf/99-user_defined_properties.conf is correct. You should be able to connect to the Spark-shell be running the following command.
MASTER=<your-spark-master-url-here> bin/spark-shell
</your-spark-master-url-here>
In the Spark’s standalone mode this url should look something like:
spark://<master-machine-ip>:7077
</master-machine-ip>
Generally it is better to use the IP address of Master node instead of the alphabetic hostname that is provided by spark master for e.g spark://Macs-MacBook-Pro.local:7077
