Description

SAMZA-717 (Expose the TaskNameGrouper API) has a factory to pick the Container grouper. There is a factory imeplentation of GroupByContainerCount. However it does not get the container count correctly. It uses config.getInt(JobConfig.JOB_CONTAINER_COUNT, 1). However if the user defines the number of containers by using the "yarn.container.count" config (which is deprecated but still supported) it will not pick the right number.
