> Currently, YARN NM passes JAVA_HOME, HDFS_HOME, CLASSPATH environments before launching Docker container no matter if ENTRY_POINT is used or not. This will overwrite environments defined inside Dockerfile (by using \{{ENV}}). For Docker container, it actually doesn't make sense to pass JAVA_HOME, HDFS_HOME, etc. because inside docker image we have a separate Java/Hadoop installed or mounted to exactly same directory of host machine.
