SAP Vora Thrift Server Error: Instantiating dialect 'sapsql' failed

Question

我已经部署了 cloudera CDH 5.13.1 集群 SAP Vora 1.4 Patch 4。

当我启动 Vora thrift 服务器时，一切看起来都很好，但是一旦我启动 SAP Vora tools 并登录，就会出现以下错误：

17/12/20 11:26:52 ERROR thriftserver.SparkExecuteStatementOperation: Error executing query, currentState RUNNING,

在安装指南中说我需要为 Hive Metastore 分配 vora 用户授权。

因为这只是 Hive 中禁用的测试设置授权，vora 用户可以在默认数据库中创建和删除表，并且具有对 Hive 仓库位置的写入权限。

我该如何解决？

此问题是由于与 CDH 5.13 和 Vora 1.4 补丁 4 不兼容造成的。SAP 目前正在调查此问题。

您是否可以选择升级到更新的 Vora 版本？当前版本是 Vora 2.1。从 2.0 版本开始，Vora 部署在 Kubernetes 集群中，而不是 Hadoop 集群中。这可能有助于克服此 CDH 依赖性问题。
