zookeeper设置了/的权限 kafka注册到zookeeper异常

因为对网络安全监测，发现zookeeper没有对/节点设权限，所以就通过ACL设置了/的权限,设置权限后导致kafka注册不到对应的zookeeper的brokers上。

异常信息如下：

org.I0Itec.zkclient.exception.ZkException: org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth
    at org.I0Itec.zkclient.exception.ZkException.create(ZkException.java:68)

    at kafka.Kafka.main(Kafka.scala)
Caused by: org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth
    at org.apache.zookeeper.KeeperException.create(KeeperException.java:113)

尝试的方法如下：

1）设置了zookeeper+kafka的SASL，测试后感觉与这个问题无关，注册节点依然注册不上去。
