報錯信息如下：
spark02: failed to launch: nice -n 0 /usr/local/softwareInstall/spark-2.1.1-bin-hadoop2.7/bin/spark-class org.apache.spark.deploy.worker.Worker --webui-port 8081 spark://spark01:7077

spark02: JAVA_HOME is not set

摸不着頭腦
預算網上求解，終於得到解決方案
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.
也就是說在每一個worker的root用戶下/root/.bashrc的文件后邊導入jdk 的路徑
然后我就這樣試了一下，發現問題居然沒有解決，還是報那個錯誤，然后又找了一會答案還是沒找到
於是我就想網上是說在root用戶下添加java路徑，我用的不是root用戶，於是我就在我用的那個用戶的目錄下的.bashrc文件添加Java路徑，然后問題解決。
