hbase ZooKeeper create failed after 4 attempts

hbase的master的备份机，启动不了了。报以下错误：

2019-11-08 10:19:51,950 ERROR [main] zookeeper.RecoverableZooKeeper: ZooKeeper create failed after 4 attempts
2019-11-08 10:19:52,820 INFO [main] zookeeper.ZooKeeper: Session: 0x0 closed
2019-11-08 10:19:52,820 ERROR [main] master.HMasterCommandLine: Master exiting

解决问题的思路：

1，发现hbase进程没起来后，第一时间查日志

2，检查HBASE_MANAGES_ZK=false，我的zk是独立安装的

3，查看端口：

kafka停掉了，hbase进程没起来，本机的zk停掉了，但是根zk集群的连接还有这么多，不正常。

前段时间装了kafka eagle，会不会是因为它呢？停掉kafka eagle，在启动hbase，好了。
