我们已将hdp cluster升级到3.1.1.3.0.1.0-187,并发现:
hive有一个新的元存储位置
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

你能帮助我了解发生了什么事以及如何解决这个问题吗?
更新:
配置:

从hive-site.xml:

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

代码如下所示:

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")

spark提交:

    --deploy-mode client \
    --driver-memory 2g \
    --driver-cores 4 \
    --executor-memory 2g \
    --num-executors 10 \

我有一个回溯技巧为这一个虽然免责声明,它绕过了游侠权限(不要责怪我,如果你招致一个管理员的愤怒)。
与Spark壳配合使用

export HIVE_CONF_DIR=/usr/hdp/current/hive-client/conf
spark-shell --conf "spark.driver.extraClassPath=/usr/hdp/current/hive-client/conf"

与sparkyr一起使用

Sys.setenv(HIVE_CONF_DIR="/usr/hdp/current/hive-client/conf")
conf = spark_config()
conf$'sparklyr.shell.driver-class-path' = '/usr/hdp/current/hive-client/conf'

它应该工作的节俭服务器,但我还没有测试。

看起来这是一个没有实现的spark特性。但我发现,从3.0开始使用spark和hive的唯一方法是使用horton的hivewarehouseconnector。这里是文档。霍顿社区的好向导。在spark开发人员准备好自己的解决方案之前,我不回答这个问题。
