如果动物园管理员设置好了，Kafka就不会启动。acl设置为true

Question

我有一套kerberize Zookeeper和kerberize Kafka，zookeeper.set.acl设置为false时效果很好。当我尝试以参数设置为true启动Kafka时，我在zookeeper日志中得到了以下信息：

Nov 12 13:36:26 <zk host> docker:zookeeper_corelinux_<zk host>[1195]: [2019-11-12 13:36:26,625] INFO Client attempting to establish new session at /<kafka ip>:54272 (org.apache.zookeeper.server.ZooKeeperServer)

Kafka和佐克佩尔都在docker中跑步（使用Confluent的图片）

以下是Zookeeper配置（通过环境变量传入）：

"ZOOKEEPER_AUTHPROVIDER_1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider",
"KAFKA_OPTS=-Djava.security.auth.login.config=/etc/zookeeper/secrets/zookeeper_jaas.conf -Dzookeeper.kerberos.removeHostFromPrincipal=true -Dzookeeper.kerberos.removeRealmFromPrincipal=true",
"ZOOKEEPER_SERVER_ID=1",
"ZOOKEEPER_REQUIRECLIENTAUTHSCHEME=SASL",
"KAFKA_JMX_HOSTNAME=<zk host>",
"ZOOKEEPER_INIT_LIMIT=10",
"ZOOKEEPER_JASSLOGINRENEW=3600000",
"ZOOKEEPER_LOG4J_PROP=DEBUG,ROLLINGFILE",
"ZOOKEEPER_MAX_CLIENT_CNXNS=0",
"ZOOKEEPER_SERVERS=0.0.0.0:2888:3888;zookeeper2:2888:3888;zookeeper3:2888:3888",
"ZOOKEEPER_DATA_DIR=/data/zookeeper",
"ZOOKEEPER_CLIENT_PORT=2181",
"KAFKA_JMX_PORT=55554"

动物园管理员JAAS：

Server {
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    storeKey=true
    doNotPrompt=true
    useTicketCache=false
    keyTab="/etc/zookeeper/secrets/kfkzkp.keytab"
    principal="zookeeper/<zk host>@REALM";
};

这是Kafka配置：

"KAFKA_ZOOKEEPER_SET_ACL=true",
"KAFKA_DEFAULT_REPLICATION_FACTOR=3",
"KAFKA_SASL_MECHANISM_INTER_BROKER_PROTOCOL=GSSAPI",
"KAFKA_ADVERTISED_LISTENERS=SASL_SSL://<kafka host>:9092",
"KAFKA_OPTS=-Djava.security.auth.login.config=/etc/kafka/secrets/kafka_server_jaas.conf",
"KAFKA_ZOOKEEPER_CONNECT=zookeeper1:2181,zookeeper2:2181,zookeeper3:2181",
"KAFKA_ALLOW_EVERYONE_IF_NO_ACL_FOUND=true",
"KAFKA_SSL_CLIENT_AUTH=required",
"KAFKA_CONFLUENT_SUPPORT_METRICS_ENABLE=False",
"KAFKA_LOG_DIRS=/data/kafka",
"KAFKA_SASL_KERBEROS_SERVICE_NAME=kafka",
"KAFKA_SSL_TRUSTSTORE_FILENAME=root-ca-certificate.jks",
"KAFKA_JMX_HOSTNAME=<kafka host>",
"KAFKA_MIN_INSYNC_REPLICAS=2",
"KAFKA_JMX_PORT=55555",
"KAFKA_SSL_KEY_CREDENTIALS=redacted",
"KAFKA_AUTHORIZER_CLASS_NAME=kafka.security.auth.SimpleAclAuthorizer",
"KAFKA_SUPER_USERS=User:superuser;User:me",
"KAFKA_SSL_KEYSTORE_FILENAME=<kafka host>.jks",
"KAFKA_SSL_KEYSTORE_CREDENTIALS=redacted",
"KAFKA_SSL_TRUSTSTORE_CREDENTIALS=redacted",
"KAFKA_AUTO_CREATE_TOPICS_ENABLE=true",
"KAFKA_SASL_ENABLED_MECHANISMS=GSSAPI,PLAIN",
"KAFKA_LISTENERS=SASL_SSL://<kafka host>:9092",
"KAFKA_SECURITY_INTER_BROKER_PROTOCOL=SASL_SSL",

Kafka·JAAS:

// Zookeeper client authentication
Client {
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    storeKey=true
    doNotPrompt=true
    useTicketCache=false
    serviceName=kafka
    keyTab="/etc/kafka/secrets/kfkzkp.keytab"
    principal="kafka/<kafka host>@REALM";
};

我看这个已经有一段时间了，已经浏览了谷歌上的大部分相关内容（包括stackoverflow的一些链接）。欢迎提出任何建议。

Answer 1

想出来了。由于某些原因，有些变量没有从环境中正确拾取。我昨天通过ZOOKEEPER_KERBEROS_REMOVEREALMFROMPRINCIPAL（和REMOVEHOSTFROMPRONCIPAL）注意到了这一点。所以我试着移动这些

"ZOOKEEPER_AUTHPROVIDER_1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider",
"ZOOKEEPER_REQUIRECLIENTAUTHSCHEME=SASL",

进入

KAFKA_OPTS: "-Djava.security.auth.login.config=/etc/zookeeper/secrets/zookeeper_jaas.conf -Dzookeeper.kerberos.removeHostFromPrincipal=true -Dzookeeper.kerberos.removeRealmFromPrincipal=true -Dzookeeper.authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider -Dzookeeper.requireClientAuthScheme=sasl"

这就解决了。
