The Resource Manager can be launched or stopped from either the command line or the Marathon UI.

Launching from the Command Line

To start the Resource Manager, run the YARN daemon from the command line:

yarn-daemon.sh start resourcemanager

 

To shut down he Resource Manager, run the YARN daemon from the command line:

yarn-daemon.sh stop resourcemanager

 

Launching from Marathon

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:

 cd hadoop-2.7.1/sbin && yarn-daemon.sh start resourcemanager

 

Alternatively, when launching the Resource Manager in an HA environment, specify the yarn.resourcemanager.hostname property. The hostname is the ID field specified when launching a Marathon application.

env && export YARN_RESOURCEMANAGER_OPTS=-Dyarn.resourcemanager.hostname=rmapp.marathon.mesos && yarn resourcemanager

Some applications might require the yarn.resourcemanager.hostname property to be specified explicitly as a command line option.
