Fail to overwrite mapred conf at cube level

[? ?]

Hey,


I tried to overwrite some mapred conf at cube level - Advanced Setting, but per 
configuration of mapred job in Job UI, they did not take effect. what is the 
wrong, or Kylin does not support to overwrite the conf items?


   "kylin.job.mr.config.override.mapreduce.reduce.cpu.vcores": "8",
    "kylin.job.mr.config.override.mapreduce.map.cpu.vcores": "8",
