java - 通过 Java 中的 Keytab 进行 Kerberos 身份验证的问题

Question

我正在尝试使用 Java 从我的本地计算机创建一个 kerberos 安全的 Hadoop 集群。

这是我尝试做的事情:

public static void hbase() throws IOException {
    System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
    final Configuration hBaseConfig = HBaseConfiguration.create();
    hBaseConfig.setInt("timeout", 120000);
    hBaseConfig.set("hbase.zookeeper.quorum", <zookeeper_quorum_address>);
    hBaseConfig.set("hbase.zookeeper.property.clientPort", "2181");
    hBaseConfig.set("hadoop.security.authentication", "kerberos");
    hBaseConfig.set("hbase.security.authentication", "kerberos");
    hBaseConfig.set("hbase.master.kerberos.principal", <kerberos.hbase.principal>);
    hBaseConfig.set("hbase.regionserver.kerberos.principal", <kerberos.hbase.principal>);
    hBaseConfig.set("hbase.master.keytab.file", "hbase.keytab");
    hBaseConfig.set("hbase.regionserver.keytab.file", "hbase.keytab");
    UserGroupInformation.setConfiguration(hBaseConfig);
    UserGroupInformation ugi = UserGroupInformation.loginUserFromKeytabAndReturnUGI(<principalName>,
            path_to_keytab_on_local_fs);
}

我从集群管理员那里获得了 zookeeper quorum、hbase principal 等的值，所以我相当确定它们是准确的。我还通过在集群上使用 kinit 获取票证来验证我的 key 表

这是错误跟踪:

我还尝试了另一种方法，重新调整 UserGroupInformation与 SecurityUtil

 SecurityUtil.login(hBaseConfig, <keytab>, <principal name>);

    SecurityUtil.doAsCurrentUser(new PrivilegedExceptionAction<Void>() {
         .............
     }

使用这种方法，控制台输出显示 Session Established ，但除此之外，执行仍在继续，没有任何日志/控制台输出，我必须强制终止它。

我真的很感激一些洞察力来帮助解决这个问题。

你可以尝试类似的东西

System.setProperty("java.security.krb5.conf", "/etc/krb5.conf")
System.setProperty("sun.security.krb5.debug", "true")

hbaseConf = HBaseConfiguration.create()
hbaseConf.set("hbase.connection.timeout", "5000")
hbaseConf.set("zookeeper.znode.parent", "/hbase")
hbaseConf.set("hbase.zookeeper.quorum", zkQuorum)
hbaseConf.set("hbase.zookeeper.property.clientPort", zkPort)
hbaseConf.set("hbase.client.retries.number", Integer.toString(1))
hbaseConf.set("zookeeper.session.timeout", Integer.toString(60000))
hbaseConf.set("zookeeper.recovery.retry", Integer.toString(1))
hbaseConf.addResource(new Path(System.getenv("PWD") + "/" + "core-site.xml"))
hbaseConf.addResource(new Path(System.getenv("PWD") + "/" + "hbase-site.xml"))
hbaseConf.set("hbase.rpc.controllerfactory.class", "org.apache.hadoop.hbase.ipc.RpcControllerFactory")
hbaseConf.set("hadoop.security.authentication", "kerberos")
hbaseConf.set("hbase.security.authentication", "kerberos")
hbaseConf.set("hbase.master.kerberos.principal", masterKerberosPrincipal)
hbaseConf.set("hbase.regionserver.kerberos.principal", regionServerKerberosPrincipal)

UserGroupInformation.setConfiguration(hbaseConf)



 val loggedUGI = UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, localPath.toString)

loggedUGI.doAs(new PrivilegedAction[Void] {
    override def run() = {
        val connection = getConnection()
        val table = getTable(connection, fullTableName)
        try {

.... HBASE STUFF

        } finally {
            table.close()
            connection.close()
        }
        null
    }
})
