Launching the Myriad Environment
To start Myriad, run the YARN daemon from the command line:
| Code Block |
|---|
yarn-daemon.sh start resourcemanager |
To shut down Myriad, run the YARN daemon from the command line:
| Code Block |
|---|
yarn-daemon.sh stop resourcemanager |
Alternatively, start and stop Myriad from the Marathon UI. See Marathon: Application Basics for more information. For example, create an application to start the Resource Manager:
| Code Block |
|---|
cd hadoop-2.7.1/sbin && yarn-daemon.sh start resourcemanager |
Launching the Myriad Environment
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 areThe Myriad environment is launched and monitored by starting the Mesos, Marathon, and Myriad applications using the following ports:
| Application | Port | Syntax |
|---|---|---|
| Marathon | 8080 | http://<IP address>:8080 |
| Mesos | 5050 | http://<IP address>:5050. Use the 5050 port and Frameworks directory. For example: http://<ip <IP address>:5050/#/frameworks (http://10.141.141.20:5050/#/frameworks) |
| Myriad | 8192 | http://<IP address>:8192. For example: http://<ip <IP address>:8192/ (http://10.141.141.20:8192/)
