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.
