Zookeeper中的SASL身份验证异常

问题描述

自从我们迁移到zookeeper 3.5.7并启用了SASL身份验证以来，在生产者的Zookeeper登录中看到以下错误。

无法使用SASL进行身份验证 javax.security.sasl.SaslException。

堆栈跟踪如下：

2020-07-08 00:37:10,576 - ERROR [LearnerCnxAcceptor-pr3-alloyp-lapp302.prz.apple.com/10.57.16.137:xxxx:SaslQuorumAuthServer@132] - Failed to authenticate using SASL
javax.security.sasl.SaslException: Learner not trying to authenticate and authentication is required
    at org.apache.zookeeper.server.quorum.auth.SaslQuorumAuthServer.authenticate(SaslQuorumAuthServer.java:82)
    at org.apache.zookeeper.server.quorum.LearnerHandler.<init>(LearnerHandler.java:198)
    at org.apache.zookeeper.server.quorum.Leader$LearnerCnxAcceptor.run(Leader.java:403). 

我看着动物园管理员jaas conf，似乎什么也没脱颖而出。

QuorumServer {
org.apache.zookeeper.server.auth.DigestLoginModule required
user_admin="xxxx";
};

QuorumLearner {
org.apache.zookeeper.server.auth.DigestLoginModule required
username="admin"
password="xxxx";
};

Server {
org.apache.zookeeper.server.auth.DigestLoginModule required
user_test="xxxx";
};

Client {
org.apache.zookeeper.server.auth.DigestLoginModule required
username="test"
password="xxxx";
};

然后，我查看了zoo.cfg并将其与open source documentation进行了比较，但没有配置问题，我可以缩小范围。

很高兴获得解决此问题的建议。
