 ## Prerequisites
 
 1. Before the extension is installed, the prerequisites mentioned [here](https://community.appdynamics.com/t5/Knowledge-Base/Extensions-Prerequisites-Guide/ta-p/35213) need to be met. Please do not proceed with the extension installation if the specified prerequisites are not met 
-2. This extension will fetch metrics from Spark applications running in a cluster setup. Spark application metrics persist only as long as the application is alive, which makes it essential to have a repository or metric dump which stores these metrics even after the application has been terminated. 
-3. Spark offers a number of metric dumps - REST, JMX, CSV etc. This extension uses a REST dump in the form of a Spark History Server. Please refer to the next section for instructions on how to configure and use the History Server. 
-4. The extension needs to be able to connect to spark history server in order to collect and send metrics. To do this, you will have to either establish a remote connection in between the extension and the product, or have an agent on the same machine running the product in order for the extension to collect and send the metrics.  
-5. More general Spark related information can be found on the Spark homepage - http://spark.apache.org/docs/3.0.0/ 
+2. Download and install [Apache Maven](https://maven.apache.org/) which is configured with `Java 8` to build the extension artifact from source. You can check the java version used in maven using command `mvn -v` or `mvn --version`. If your maven is using some other java version then please download java 8 for your platform and set JAVA_HOME parameter before starting maven.
