Can you run apache spark on apache hadoop?

Spark can run on Apache Hadoop, Apache Mesos, Kubernetes, on its own, in the cloud—and against diverse data sources. One common question is when do you use Apache Spark vs. Apache Hadoop?
Moreover,
Spark may be the newer framework with not as many available experts as Hadoop, but is known to be more user-friendly. In contrast, Spark provides support for multiple languages next to the native language (Scala): Java, Python, R, and Spark SQL. This allows developers to use the programming language they prefer.
Also, In the Cloudera Manager Admin Console, go to the Hive service. Search for the Spark On YARN Service. To configure the Spark service, select the Spark service name. To remove the dependency, select none. Click Save Changes. Go to the Spark service. Add a Spark gateway role to the host running HiveServer2.
Keeping this in consideration,
Apache Storm is the stream processing engine for processing real time streaming data while Apache Spark is general purpose computing engine which provides Spark streaming having capability to handle streaming data to process them in near real-time.
Consequently,
The differences between Apache Hive and Apache Spark SQL is discussed in the points mentioned below: Hive is known to make use of HQL (Hive Query Language) whereas Spark SQL is known to make use of Structured Query language for processing and querying of data
