在带有 Spark Controller 1.6 PL1 的 MapR 5.1/Spark 1.5.2 上的 SAP HANA Vora 1.2 中：
我已经配置了 Spark 控制器并启动了服务器。成功加载表，可以从 VORA 工具中看到。
在 SAP HANA Studio 中，我现在可以在其中看到我创建的文件夹“spark_velocity”和“M_JCUST”。当我尝试使用“添加为虚拟表”选项添加此表我的 HANA 文件夹时，我收到一个错误：
SAP DBTech JDBC: [476]: invalid remote object name:
Unable to retrieve remote metadata for
SparkSQL.spark_velocity.SparkSQL.spark_velocity.M_JCUST: line 0 col 0 (at pos 0)
/var/log/hanaes 如下：

此问题与以下发布的问题相同： SAP HANA Vora 1.2：无法在 HANA Studio 中加载为虚拟表
但是，我使用 SAP HANA SPS12、带有 MapR 支持的 Spark Controller 1.6 PL1 并正确替换了 spark-sap-datasources-1.2.33-assembly.jar。
关于这个错误的任何建议？
