Launching the Myriad Environment

To launch Myriad, run the YARN daemon from the command line:

Code Block
yarn-daemon.sh start resourcemanager

 

Stopping Myriad

To shut down Myriad, run the YARN daemon from the command line:

The Myriad environment is established by running an initial application for the resource manager. This initial application name is specified in the yarn-site.xml file with the the yarn.resourcemanager.hostname property and the value, <app-ID>.<framework>.mesos.

For example, if the value of  yarn.resourcemanager.hostname property is rm.marathon.mesos:

  • rm - The ID given to the Resource Manager when launched using Marathon. Mesos-DNS constructs the Resource Manager hostname using the ID.
  • marathon - The Mesos framework

If you are using Marathon, launch Marathon and run an initial Resource Manager application. See Starting Resource Manager for more information.


Ports

The ports used by Mesos, Marathon, and Myriad are:

ApplicationPortSyntax
Marathon8080http://<IP address>:8080
Mesos5050http://<IP address>:5050. Use the 5050 port and Frameworks directory. For example: http://<IP address>:5050/#/frameworks (http://10.141.141.20:5050/#/frameworks)
Myriad8192

http://<IP address>:8192. For example: http://<IP address>:8192/ (http://10.141.141.20:8192/)

  • Without the Mesos-DNS service, this IP is slave node's IP address where the Resource Manager is running.
  • With the Mesos-DNS service, Mesos-DNS discovers the node where the Resource Manager is running by using Mesos DNS FQDN (<app-name>.<framework>.mesos).
