使用 java 客户端连接到安全的 Hbase

Question

我正在尝试使用 kerberos 连接安全的 hbase。 它是一个部署到 hdp3 集群中的 hbase。 确切地说，我正在尝试从集群外部的主机访问 java 客户端。

这是我的代码：

System.setProperty("java.security.krb5.conf","/etc/krb5.conf");
        System.setProperty("sun.security.krb5.debug", "true");
        System.setProperty("java.security.debug", "gssloginconfig,configfile,configparser,logincontext");
        System.setProperty("java.security.auth.login.config", "hbase.conf");

        Configuration conf = HBaseConfiguration.create();

        String principal="user@REALM";
        File keytab = new File("/home/user/user.keytab");

        UserGroupInformation.setConfiguration(conf);
        UserGroupInformation ugi = UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, keytab.getAbsolutePath());

        ugi.doAs(new PrivilegedAction<Void>() {
            @Override
            public Void run() {

                try {

                    TableName tableName = TableName.valueOf("some_table");
                    final Connection conn = ConnectionFactory.createConnection(conf);
                    System.out.println(" go ");
                    Table table = conn.getTable(tableName);
                    Result r = table.get(new Get(Bytes.toBytes("some_key")));
                    System.out.println(r);

                } catch (IOException e) {
                    e.printStackTrace();
                }

                return null;
            }
        });

    }

这是我的 jaas 文件配置：

Client {
  com.sun.security.auth.module.Krb5LoginModule required
  useKeyTab=true
  useTicketCache=false
  keyTab="/home/user/user.keytab"
  principal="user@REALM";
};

所有 zookeeper 和其他配置均取自 ambari 提供的 hbase-site.xml 文件。

我没有收到任何错误，只是客户端进入了一个无限循环，其跟踪如下：

好的，我得到了这个错误，只是我没有等待足够的时间：

谢谢。

Answer 1

最后添加这个道具它起作用了：

        conf.set("hadoop.security.authentication", "kerberos");

这是我的最终代码：

    public static void main(String[] args) throws IOException, InterruptedException {
        System.setProperty("java.security.krb5.conf", "/etc/krb5.conf");

        Configuration conf = HBaseConfiguration.create();
        conf.set("hadoop.security.authentication", "kerberos");

        String principal = "user@REALM";

        UserGroupInformation.setConfiguration(conf);
        UserGroupInformation ugi = UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, "/home/user/principal.keytab");

        Connection conn = ugi.doAs(new PrivilegedExceptionAction<Connection>() {
            @Override
            public Connection run() throws Exception {
                return ConnectionFactory.createConnection(conf);
            }
        });

        TableName tableName = TableName.valueOf("some_table");
        Table table = conn.getTable(tableName);
        Result r = table.get(new Get(Bytes.toBytes("some_key")));

        System.out.println("result: " + r);

    }

Answer 2

我有同样的问题； 就我而言，当我提交 spark 作业时，我在 spark-submit 命令中包含了 hadoop* 和 hbase* jars； 经过一番检查，我注意到我在我的纱线集群中包含了 hadoop* 和 hbase* jars，它们与相同版本的 hbase/hadoop 不匹配。 那些 jars 的区别很小，但它搞砸了 kerberos 身份验证
