A workaround is the usage of the property spark.yarn.access.hadoopFileSystems. 在 YARN上运行Spark需要使用YARN支持构建的Spark的二进制分发。二进制发行版可以从项目网站的 下载页面下载 。要自己构建 Spark,请参阅 Building Spark 。 为了让从 YARN端访问Spark运行时jar,你可以指定 spark.yarn.archive 或 spark.yarn.jars 。有关详细信息,请参阅 Spark属性 。 In this tutorial I will show you how to use Kerberos/SSL with Spark integrated with Yarn. Yes @dbompart both the Clusters are in HA Configuration and running HDP 2.6.3. we added the property spark.yarn.access.namenodes in spark submit. 10.存 在的问题 2.1 read 、 save() Spark 配置 : spark.yarn.access.namenodes or spark.yarn.access.hadoopFileSystems 客户端对 ns-prod 和 ns 进行 配置 , 分别指向主集群和实时集群 ResourceManager 也需要添加两个集群的 ns 信息 Spark 配置必须包含以下行: spark.yarn.security.credentials.hive.enabled false spark.yarn.security.credentials.hbase.enabled false 必须取消设置配置选项spark.yarn.access.hadoopFileSystems. 各位大神好,最近尝试使用spark on yarn 的模式访问另一个启用了kerberos的hadoop集群上的数据,在程序执行的集群上是有一个用户的票证的,local模式下执行程序是能够访问的,但是指定了--master yarn 之后,不管是client模式还是cluster模式都报下面的错误,在网上苦寻无果,只好前来求助: spark.yarn.security.credentials.hive.enabled false spark.yarn.security.credentials.hbase.enabled false 設定オプション spark.yarn.access.hadoopFileSystems は未設定でなければなりません。 Kerberosのトラブルシューティング. For Spark, please add the following property to spark-defaults.conf and restart Spark and YARN: spark.yarn.access.hadoopFileSystems = Replace with the actual Alluxio URL starting with alluxio://. Hadoop/Kerberos 問題は"困難"になる可能性があります。 Now we are able to list the contents as well as Write files also across 2 clusters Thank you. I will use self signed certs for this example. ## Kerberos 故障排查 调试 Hadoop/Kerberos 问题可能是 “difficult 困难的”。 Before you begin ensure you have installed Kerberos Server and Hadoop . 如果设置,则此配置将替换, spark.yarn.jars 并且该存档将用于所有应用程序的容器中。 归档文件应该在其根目录中包含jar文件。 和前面的选项一样,存档也可以托管在HDFS上以加速文件分发。 spark.yarn.access.hadoopFileSystems (没有) In single master mode, this URL can be alluxio://:/. But even after that we are still confused why the FileSystem object has SIMPLE Authentication not KERBEROS Athenticaion? The configuration option spark.yarn.access.namenodes must be unset. Spark version was 1.6.
