We have upgraded HDP cluster to 3.1.1.3.0.1.0-187 and have discovered:
- Hive has a new metastore location
- Spark can't see Hive databases
In fact we see:
org.apache.spark.sql.catalyst.analysis.NoSuchDatabaseException: Database ... not found
Could you help me understanding what has happened and how to solve this?
Update:

And from hive-site.xml:
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/warehouse/tablespace/managed/hive</value>
</property>
Code looks like:
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-submit:
--master yarn \
--deploy-mode client \
--driver-memory 2g \
--driver-cores 4 \
--executor-memory 2g \
--num-executors 10 \
--executor-cores 3 \

Looks like this is a not implemented Spark feature. But the only one way to use Spark and Hive since 3.0 that I found is to use HiveWarehouseConnector from Horton. Documentation here. And good guide from Horton Community here. I leave the question unanswered until Spark developers have prepared an own solution.
I've got a bit of a throwback trick for this one although disclaimer, it bypasses the ranger permissions (don't blame me if you incur the wrath of an admin).
To use with the spark-shell
export HIVE_CONF_DIR=/usr/hdp/current/hive-client/conf
spark-shell --conf "spark.driver.extraClassPath=/usr/hdp/current/hive-client/conf"
To use with sparklyR
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'
It should work for the thriftserver too but I have not tested.
