Starting Resource Manager
A Resource Manager for Myriad must be launched before the Myriad UI becomes available.
About this task
IMPORTANT This component is deprecated. Hewlett Packard
Enterprise recommends using an alternate product. For more information, see Discontinued Ecosystem Components.
The initial Resource
Manager is started from Marathon. In addition, only one (1) Resource Manager can be
launched on a cluster. NOTE Starting the Resource Manager from the command line results
in an error, see Troubleshooting Myriad for a workaround.
To start the Resource Manager:
Procedure
- Launch Marathon with http://hostname:8080.
- Click on New App.
-
Create a new application for the resource manager and specify:
- ID - Default: rm
- CPU - 0.2 minimum
- Memory - 2048 minimum
- Instances - 1 only
- Command -
env && yarn resourcemanager
For example:
Table 1. Application Parameters Parameter Example ID rm CPU 0.2 Memory 2048 Instances 1 Command env && yarn resourcemanager
IMPORTANT Only one instance of Myriad Resource Manager can be running. Scaling up instances (specifying more than one instance) may result in unpredictable behavior. Creating a new Myriad application from Marathon results in a new framework. -
Access the Myriad UI with <hostname>:8192
If you have multiple nodes in your cluster, Myriad may be started on any one of the nodes. To obtain the Myriad host, access the Mesos UI (
http://<hostname>:5050
) and check the Active Tasks > Hosts panel.If the Mesos-DNS entry is added on your local machine, the host can be accessed with the following address:
http://rm.marathon.mesos:8192
