Anyone experienced similar issues? we are using HDP 3.1 Connection details: spark-shell --master yarn --driver-memory 7g --executor-memory 7g --conf spark.yarn.queue=SPARK --conf spark.sql.hive.hiveserver2.jdbc.url="jdbc:hive2:<servername>;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2-interactive" spark.datasource.hive.warehouse.metastoreUri=thrift:<servername>:9083,thrift spark.hadoop.hive.zookeeper.quorum="<servername>:2181" spark.hadoop.hive.llap.daemon.service.hosts=@llap0 spark.security.credentials.hiveserver2.enabled=false --jars /usr/hdp/3.1.0.0-78/hive_warehouse_connector/hive-warehouse-connector-assembly-1.0.0.3.1.0.0-78.jar commands scala> val hive = com.hortonworks.spark.sql.hive.llap.HiveWarehouseBuilder.session(spark).build() hive: com.hortonworks.spark.sql.hive.llap.HiveWarehouseSessionImpl = com.hortonworks.spark.sql.hive.llap.HiveWarehouseSessionImpl@194eae3e scala> hive.showDatabases().show(100, false) +------------------+ |database_name | +------------------+ |default | |information_schema| |sandbox | |sys | +------------------+ The fact that showdatabases works fine suggests that it is able to connect to hive metastore without any issues. But the moment we try any aggregate functions like below, its failing.
