windows10本地联调zk环境报异常SASL config status: Will not attempt to authenticate using SASL (unknown error)

SASL config status: Will not attempt to authenticate using SASL (unknown error)
报错:
org.apache.zookeeper.ClientCnxn$EndOfStreamException: Unable to read additional data from server sessionid 0x108e8afac8f0077, likely server has closed socket
报错:
org.apache.zookeeper.KeeperException$OperationTimeoutException: KeeperErrorCode = OperationTimeout
提示:
SASL config status: Will not attempt to authenticate using SASL (unknown error)
原因:
zookeeper默认使用了ZooKeeperSaslClient,而这个过程中调用了getHostName方法,这个方法会对传进去的字符串进行域名解析,即使是一个ip地址也会进行解析,而dns解析的快慢和服务器配置有关系,从而造成程序阻塞。
解决:
可以通过在hosts文件添加上zookeeper的ip地址,使得getHostName可以直接使用hosts里面的dns结果。
win10 hosts目录:C:\Windows\System32\drivers\etc\HOSTS
保存 ,完美解决连接超时问题
