apache-spark - 带有 Hive Metastore 3.1.0 的 Apache Spark 2.3.1

Question

我们已将 HDP 集群升级到 3.1.1.3.0.1.0-187 并发现:

Hive 有一个新的 Metastore 位置

Spark 看不到 Hive 数据库

事实上我们看到:

org.apache.spark.sql.catalyst.analysis.NoSuchDatabaseException: Database ... not found

你能帮我理解发生了什么以及如何解决这个问题吗？

更新:

配置:

来自 hive-site.xml:

<property>
  <name>hive.metastore.warehouse.dir</name>
  <value>/warehouse/tablespace/managed/hive</value>
</property>

代码如下:

val spark = SparkSession
  .builder()
  .appName(getClass.getSimpleName)
  .enableHiveSupport()
  .getOrCreate()
...
dataFrame.write
  .format("orc")
  .options(Map("spark.sql.hive.convertMetastoreOrc" -> true.toString))
  .mode(SaveMode.Append)
  .saveAsTable("name")

看起来这是一个未实现的 Spark feature .但是我发现自 3.0 以来使用 Spark 和 Hive 的唯一方法是使用 HiveWarehouseConnector来自霍顿。文档 here .来自霍顿社区的好指南 here .
在 Spark 开发人员准备好自己的解决方案之前，我没有回答这个问题。
