Description

Need to document SLIDER-1201.

A new property yarn.resource.normalization.enabled is being introduced which needs to be set in the app's resources definition. By default it is "true" (which was the behavior all along, to keep backward compatibility for all existing apps). To disable normalization, set it to "false" for the desired component of the app. An example is below -

{
  "schema": "http://example.org/specification/v2.0.0",
  "metadata": {
  },
  "global": {
  },
  "components": {
    "COMMAND_LOGGER": {
      "yarn.role.priority": "1",
      "yarn.component.instances": "1",
      "yarn.resource.normalization.enabled": "false",
      "yarn.memory": "186368",
      "yarn.vcores": "1"
    },
    "slider-appmaster": {
    }
  }
}
