Hi, Unfortunately it is built with java 11 and will not work on Java 8 so. However, you can install Java 11 on only one node, along with Java 8 and let Java 8 be the default (so you do not impact any of CDP components or your programs). Then go in CM > Datagen > Configuration and set java_home_custom to the path on the node where Java 11 is installed. Datagen should start with it. Thanks. ... View more

Hello @sduraisankar93,   If you are facing this issue, as you said it's because you do not have imported the module.   I believe you should check this documentation on how to import HWC and use it : https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.1.4/integrating-hive/content/hive_configure_a_spark_hive_connection.html   If you are using Zeppelin, please check this : https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.1.4/integrating-hive/content/hive_zeppelin_configuration_hivewarehouseconnector.html   Note that, in Zeppelin pysark configuration could not work, so a work around is to set (via Ambari) in Zeppelin-env.sh section, this configuration : export SPARK_SUBMIT_OTPIONS="--jars usr/hdp/current/hive_warehouse_connector/hive-warehouse-connector-assembly-<version>.jar --py-files usr/hdp/current/hive_warehouse_connector/hive-warehouse-connector-assembly-<version>.zip"   Then to start a pyspark shell on your machines, launch this command : pyspark --jars /usr/hdp/current/hive_warehouse_connector/hive-warehouse-connector-assembly-jar --py-files /usr/hdp/current/hive_warehouse_connector/pyspark_hwc-.zip ...
