kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING

1、错误描述：

使用kafka自带的zookeeper，首先将zookeeper启动之后，在启动kafka的时候，报下面的异常，如下所示：

kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING
    at kafka.zookeeper.ZooKeeperClient.$anonfun$waitUntilConnected$3(ZooKeeperClient.scala:262)

2、问题解决

kafka链接zookeeper默认的18秒，如果服务器性能不行的话，估计连不上，直接将时间调大，解决问题。

# Timeout in ms for connecting to zookeeper
# zookeeper.connection.timeout.ms=18000
zookeeper.connection.timeout.ms=180000
