摸不着头脑
预算网上求解，终于得到解决方案
The solution had been quite easy and straightforward. Just added export JAVA_HOME=/usr/java/default in /root/.bashrc and it successfully started the spark services from root user without the JAVA_HOME is not set error. Hope it helps somebody facing same problem.
也就是说在每一个worker的root用户下/root/.bashrc的文件后边导入jdk 的路径
然后我就这样试了一下，发现问题居然没有解决，还是报那个错误，然后又找了一会答案还是没找到
于是我就想网上是说在root用户下添加java路径，我用的不是root用户，于是我就在我用的那个用户的目录下的.bashrc文件添加Java路径，然后问题解决。
