安装客户端修改配置后执行命令错误，提示IllegalConfigurationException: Error while parsing YAML configuration file

问题背景与现象

客户端安装成功，执行客户端命令例如yarn-session.sh命令报错，提示IllegalConfigurationException: Error while parsing YAML configuration file :81: "security.kerberos.login.principal:pippo "

[root@8-5-131-10 bin]# yarn-session.sh
2018-10-25 19:27:01,397 | ERROR | [main] | Error while trying to split key and value in configuration file /opt/flinkclient/Flink/flink/conf/flink-conf.yaml:81: "security.kerberos.login.principal:pippo " | org.apache.flink.configuration.GlobalConfiguration (GlobalConfiguration.java:160)

原因分析

配置文件flink-conf.yaml中配置项"security.kerberos.login.principal:pippo”错误。

解决办法

修改flink-conf.yaml中配置。

注意：配置项名称和值之间存在空格。
