这是日志:

Answer 1

在命令行上尝试jps命令以查看您的服务是否正在运行
您应该在那里看到Zookeeper，HBMaster和HBRegionServer

那我就摆脱了

<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/var/zookeeper</value>
  </property>

如果您没有此值，则会默认使用安全值，并且ZK可能会与此路径混淆。特别是您不清楚是否使用PC的MAC，但同时提到了两者。物理路径在PC上使用C:\xxx\表示法，但在Mac和Linux上使用file:///xxxxx/表示法。
