Description

Auxiliary service is configured with:

{
  "services": [
    {
      "name": "mapreduce_shuffle",
      "version": "2",
      "configuration": {
        "properties": {
          "class.name": "org.apache.hadoop.mapred.ShuffleHandler",
          "mapreduce.shuffle.transfer.buffer.size": "102400",
