我们需要在苏打水中使用 LDAP 对用户进行身份验证。我们尝试使用苏打水 1.6.13 和 h2O 3.14.0.2 进行配置。下面是配置：

*ldaploginmodule {
    org.eclipse.jetty.plus.jaas.spi.LdapLoginModule required
    debug="true"
    useLdaps="false"
    contextFactory="com.sun.jndi.ldap.LdapCtxFactory"
    hostname="localhost"
    port="389"
    bindDn="CN=admin,OU=Users,DC=company,DC=com"
    bindPassword="password"
    authenticationMethod="simple"
    forceBindingLogin="true"
    userBaseDn="dc=company,dc=com";
};*

使用的命令： spark-submit --class water.SparklingWaterDriver --master yarn-client --num-executors 2 --driver-memory 6g --executor-memory 4g --executor-cores 2 --conf 'spark.dynamicAllocation。 enabled=false' --conf spark.ext.h2o.log.level=DEBUG --conf spark.ext.h2o.ldap.login=true --conf spark.ext.h2o.login.conf=/home/user/ ldap.conf /home/user/sparkling-water-1.6.13/assembly/build/libs/sparkling-water-assembly_2.10-1.6.13-all.jar

但我们面临一些问题。请在下面找到错误日志。将不胜感激任何帮助。 错误：

两个附加说明：

  • 不要使用苏打水 1.6 并升级
  • 升级后，对于 LDAP conf，您需要将 LoginModlue 引用修改为ai.h2o.org.eclipse.jetty.plus.jaas.spi.LdapLoginModule required

很可能是您的环境特有的配置错误。向您组织的 LDAP/AD 专家寻求帮助。外部的任何人都不容易帮助你。

以下是我推荐的一些调试 LDAP 问题的技巧。

首先，不要直接在 Sparkling Water 中进行调试。在没有 Hadoop 或 Spark 的纯独立 H2O 中对其进行调试，因此您可以隔离问题，并且很容易看到正在发生的事情，并且您不必寻找 stdout/stderr/logs。

其次，您可以通过将以下文件添加到类路径中来启用 D​​EBUG jetty 日志级别并获取有关 ldaplogin 模块正在做什么的更多信息：

jetty-logging.properties

org.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog
org.eclipse.jetty.LEVEL=DEBUG

所以像这样运行（确保 jetty-logging.properties 在当前目录中）：

java -cp h2o.jar:. water.H2OApp -ldap_login -login_conf ldap-config-file
