问题描述
尝试安装Hadoop 3.1.1与HBase 2.3.5，安装并配置完成后，Hadoop正常运行，HBase启动Shell后运行list指令测试，出现如下错误
ERROR: org.apache.hadoop.hbase.ipc.ServerNotRunningYetException: Server is not running yet
at org.apache.hadoop.hbase.master.HMaster.checkServiceStarted(HMaster.java:2296)

解决过程
网上搜索后，几乎所有的答案都在说关闭HDFS安全模式再重启HBase：
hdfs dfsadmin -safemode leave
然而问题并未解决，于是查看HBase的MasterNode日志（位置：/usr/local/HBase/logs/hbase-hadoop-master-ethan-ubuntu.log)，发现如下报错：

Google该问题，找到的结果甚少。于是抱着试试的心态查了下百度，发现这个帖子：
启动hbase时报错object is not an instance of declaring class，有大神帮忙解答一下吗
评论区说原来Hadoop 3.1.1与HBase 2.3.5不兼容。于是重新安装Hadoop 3.2.2并配置完成，问题解决
