zookeeper报错：ERROR [main:QuorumPeerMain@86]

问题描述

启动zookeeper时，感觉一切正常，但是通过zkServer.sh status查看状态时，发现报错：

Error contacting service. It is probably not running.

通过查看 zk/logs下的文件，发现有如下报错：

ERROR [main:QuorumPeerMain@86] - Invalid config, exiting abnormally
org.apache.zookeeper.server.quorum.QuorumPeerConfig$ConfigException: Address unresolved: node01:3888 
	at org.apache.zookeeper.server.quorum.QuorumPeer$QuorumServer.<init>(QuorumPeer.java:242)
	at org.apache.zookeeper.server.quorum.flexible.QuorumMaj.<init>(QuorumMaj.java:89)

错误原因

在配置zoo.cfg文件时候，端口号后面还有空格。因为是从其他地方复制的，所以不容易发现

server.0=spark1:2888:3888(此处有空格)
server.1=spark2:2888:3888
server.2=spark3:2888:3888

解决办法：

删掉端口号后面的空格即可
