！！！更新 ！！！
最后经过数小时查看文档后，我发现了问题。事实证明，我在 Yarn 配置中缺少一些参数。
这就是我所做的：
- 在编辑器中打开 yarn-site.xml 文件或登录到 Ambari Web UI 并选择 Yarn>Config。找到属性“yarn.nodemanager.aux-services”并将“spark_shuffle”添加到其当前值。新属性名称应为“mapreduce_shuffle,spark_shuffle”。
- 添加或编辑属性“yarn.nodemanager.aux-services.spark_shuffle.class”，并将其设置为“org.apache.spark.network.yarn.YarnShuffleService”。
- 将 spark--yarn-shuffle.jar 文件（在步骤安装 Spark 程序集文件和依赖库中下载）从 Spark 复制到所有节点管理器主机中的 Hadoop-Yarn 类路径。通常，此文件夹位于 /usr/hdp//hadoop-yarn/lib 中。
- 重启 Yarn 和节点管理器
！！！！！！！！！！！！
我正在使用带有最新 Spark 控制器 (HANASPARKCTRL00P_5-70001262.RPM) 的 SAP Vora 1.2 开发人员版。我在 spark-shell 中将一张表加载到 Vora 中。我可以在 SAP HANA Studio 的“spark_velocity”文件夹中看到该表。我可以将表加载为虚拟表。问题是由于错误，我无法选择或预览表中的数据：
错误：SAP DBTech JDBC：[403]：内部错误：打开远程数据库的游标以查询“SELECT”SPARK_testtable“。”a1“，”SPARK_testtable“。”a2“，”SPARK_testtable“。”a3“FROM” spark_velocity"."testtable" "SPARK_testtable" LIMIT 200 "
这是我的 hanaes-site.xml 文件：

任何人，一些想法如何解决它？当我尝试读取 Vora 的 Hive 表时，会出现同样的错误。
