'environment' with 'env-file' specified together for service in docker-compose.yml don't work

[pasikon]

In such case key-value pairs in 'environment' sections are omitted.

For example

services:
  namenode:
    image: bde2020/hadoop-namenode:2.0.0-hadoop2.7.4-java8
    volumes:
      - namenode:/hadoop/dfs/name
    environment:
      - CLUSTER_NAME=test
    env_file:
      - ./hadoop-hive-namenode.env
    ports:
      - "50070:50070"
      - "8020:8020"

CLUSTER_NAME won't be set
