本文解决了一个关于Apache Spark集群中worker节点无法连接到master节点的问题。主要原因是hosts文件中的IP地址未正确对应到主机名，导致通信异常。 
failed to launch:nice -n 0 /usr/local/spark/bin/spark-class org.apache.spark.deploy.worker.Worker --webui-port 8081 spark://c9eee7a6c920:7077

worker节点连接不上master节点，原因是hosts里面 ip没有对应hostname

如图，日志信息也看不出什么内容。网上找了半天都是说各种加Java配置信息的，还有加Hadoop相关jar包的，但试了都没用。 直到后来试了试 spark-shell 结果打印了以下信息 百度了以下才发现原来是Scala和jdk版本兼容问题，我原来是jdk1.8.0_11，Scala2.12.11,，后来把jdk换成1.8.0_181后完美解决 附上jdk1.8.0_181，Linux的 链接：https://pan.baidu.com/s/12wDfVy_0OaZ8YwFGT70b...

错误原因 failed to launch: nice -n 0 /data/app/spark-2.4.3-bin-hadoop2.6/bin/spark-class org.apache.spark.deploy.history.HistoryServer 在开启spark 历史任务时，报了以上的错。 解决方式 是因为spark-defaults.conf spark-env.sh 在配置日志存放地址的hdfs目录时端口使用了9000 与我们hadoop下配置的hdfs目录不同，改成一样的即可。 .
