Subject Re:Flink 1.10连接hive时kerberos认证异常问题
Date Tue, 25 Feb 2020 06:31:16 GMT


Hi,
我在配置flink连接hive时,由于集群开启了Kerberos认证,经过一番探索,异常没有了。但是现在连接的时候需要我输入Kerberos用户名和密码。我理解指定了keytab文件路径后,应该不需要用户名和密码了吧?请教各位大神可能的配置问题。


security.kerberos.login.use-ticker-cache: false
security.kerberos.login.keytab: /app/flink/flink-1.10.10/kerberos/flink_test.keytab
security.kerberos.login.principal: flink_test@HADOOP.HTSC.COM
