Code Block
PUT /api/cluster/flexup      // Expands the size of the YARN cluster.

PUT /api/cluster/flexdown    // Shrinks the size of the YARN cluster.

 

Parameters include:

ParameterDescription
profileValue: zero, small, medium, large. Default: zero. The instance size in the cluster is defined in the myriad-config-default.yml file.
instancesValue: one (1) to the number of nodes in the cluster. For example, if there are 100 nodes in your cluster, you are bound by 100. If you specify more than 100, the excess is place in a pending state.
 constraintsValue: <hostname>??. Hostnames are used to define cluster boundary and to start and stop Node Managers on a predefined set of nodes.
