zookeeper報錯：ERROR [main:QuorumPeerMain@86] - Invalid config, exiting abnormally org.apache.zookeeper.server.quorum.QuorumPeerConfig$ConfigException: Address unresolved: node01:3888

問題描述

啟動zookeeper時，感覺一切正常，但是通過zkServer.sh status查看狀態時，發現報錯：

Error contacting service. It is probably not running.

通過查看 zk/logs下的文件，發現有如下報錯：

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)

錯誤原因

在配置zoo.cfg文件時候，端口號后面還有空格。因為是從其他地方復制的，所以不容易發現

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

解決辦法：

刪掉端口號后面的空格即可
