Step 4. Starting CDAP Services (Manual)

When all the packages and dependencies have been installed, and the configuration parameters set, you can start the services on each of the CDAP boxes by running the command:

$ for i in `ls /etc/init.d/ | grep cdap` ; do sudo service $i start ; done

When all the services have completed starting, the CDAP UI should then be accessible through a browser at port 11011.

The URL will be http://<host>:11011 where <host> is the IP address of one of the machines where you installed the packages and started the services.

Note: Service-specific Java heap memory settings (that override the default values) can be created by setting these environment variables:

AUTH_JAVA_HEAPMAX
KAFKA_JAVA_HEAPMAX
MASTER_JAVA_HEAPMAX
ROUTER_JAVA_HEAPMAX

such as:

$ export AUTH_JAVA_HEAPMAX="-Xmx1024m"

Add any overriding settings to a file, usually /etc/cdap/conf/cdap-env.sh. As described in CDAP Configuration, the location of this file will depend on your particular configuration.
