Apache kafka 执行ACL命令时出错：处于状态时等待连接超时：正在连接

更新ACL规则时出现ZK连接问题

./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=xxx.xxx.xx3:2181,xxx.xxx.xx2:2181,xxx.xxx.xx1:2181 --add --allow-principal User:xxxxxxxx --operation Read --topic xxxxxxxxxx

错误间歇性发生，无法确定根本原因

于2020年6月4日添加 在localhost上运行似乎太慢，无法超时

./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:xxxxxxx --operation Read --topic xxxxxxx

./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=hostxxxx001:2181,hostxxxx002:2181 --add --allow-principal User:xxxxxxx --operation Read --topic xxxxxxx

但是，导致超时的原因是针对集合运行

./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:xxxxxxx --operation Read --topic xxxxxxx

./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=hostxxxx001:2181,hostxxxx002:2181 --add --allow-principal User:xxxxxxx --operation Read --topic xxxxxxx
