Spark 2.2.0 启动时报Error while instantiating / java.net.ConnectException
我的机器：
已经安装好Hadoop Java Scala Hive
Master:192.168.244.129
Slave1.hadoop:192.168.244.128
Slave2.hadoop:192.168.244.130在之前的工作中比如：Hadoop Hive 等环境都已经配置正确
在启动用一下命令启动Spark集群时无问题：
./sbin/start-all.sh使用JPS查看:
1322 Jps
1297 Woerker1526 Jps
1452 Master接着启动spark-shell时遇到问题：

... 104 more 错误日志显示：
警告：无法载入原生Hadoop信息
警告：Hive的原生数据库Metastore配置信息丢失（注：本人Hive数据库连接的是mysql）
无法启动数据库
异常错误：实例化 Hive时候出错
下面写到无法连接到Master：9001 连接失败网上找了一大堆东西，简直是放屁
后来没办法就滚去看Spark文档
突然想到Spark 和MapReduce一样是在Hadoop上层运行的数据模型或者说是集群上运行的分布式框架，所以在运行Spark的时候先运行 hadoop看看：
hadoop/sbin/start-dfs.sh再次spark-shell ：
