/AWS1/CL_EMR=>PUTAUTOSCALINGPOLICY()

About PutAutoScalingPolicy

Creates or updates an automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates Amazon EC2 instances in response to the value of a CloudWatch metric.

Method Signature

IMPORTING

Required arguments:

iv_clusterid TYPE /AWS1/EMRCLUSTERID /AWS1/EMRCLUSTERID

Specifies the ID of a cluster. The instance group to which the automatic scaling policy is applied is within this cluster.

iv_instancegroupid TYPE /AWS1/EMRINSTANCEGROUPID /AWS1/EMRINSTANCEGROUPID

Specifies the ID of the instance group to which the automatic scaling policy is applied.

io_autoscalingpolicy TYPE REF TO /AWS1/CL_EMRAUTOSCALINGPOLICY /AWS1/CL_EMRAUTOSCALINGPOLICY

Specifies the definition of the automatic scaling policy.

RETURNING

oo_output TYPE REF TO /aws1/cl_emrputautoscplyoutput /AWS1/CL_EMRPUTAUTOSCPLYOUTPUT

Domain	/AWS1/RT_ACCOUNT_ID
Primitive Type	NUMC

Syntax Example

This is an example of the syntax for calling the method. It includes every possible argument and initializes every possible value. The data provided is not necessarily semantically accurate (for example the value "string" may be provided for something that is intended to be an instance ID, or in some cases two arguments may be mutually exclusive). The syntax shows the ABAP syntax for creating the various data structures.
