Yes , i'm using Java8 , and i found the 1.4 version provided new parameters : "containerized.master.env.ENV_VAR1" and "containerized.taskmanager.env". I change my start command from "-yD yarn.taskmanager.env.JAVA_HOME" to " -yD containerized.taskmanager.env.JAVA_HOME=/opt/jdk1.8.0_121 -yD containerized.master.env.JAVA_HOME=/opt/jdk1.8.0_121 " and it works . Thanks a lot .
