启动问题：

执行start-all.sh出现以下异常信息：

failed to launch: nice -n 0 /bin/spark-class org.apache.spark.deploy.worker.Worker --webui-port 8081 spark://master:7077

解决方案：

Just added export JAVA_HOME=/usr/java/default in /root/.bashrc

su root

vi /root/.bashrc

export JAVA_HOME=/opt/jdk1..0_171

之后尝试重新启动hadoop。
