spark2.1.0的sbin下启动start-all.sh脚本后，报如下信息，即，

master的日志内容如下：

[hadoop@hadoop001 ~]$ tail -100f /home/hadoop/app/spark-2.1.0-bin-2.6.0-cdh5.7.0/logs/spark-hadoop-org.apache.spark.deploy.master.Master-1-hadoop001.out

但master没看到内存注入和core的注入的信息。

worker的比较简单就是个：JAVA_HOME is not set

我查看了环境变量~/.bash_profile下有JAVA_HOME，即，

export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_161

export PATH=$PATH:$JAVA_HOME/bin

这样改了后，不报JAVA_HOME is not set的问题了，日志最后几行为，即，
