@yjiang i have seen this exception happen when the druid broker/historical are returning exceptions instead of query results. The way to debug this, i would send via curl command some test query to druid. You can do an explain on the query you posted that will show you the actual druid query, copy that and send it via curl ` curl -X POST '<queryable_host>:<port>/druid/v2/?pretty' -H 'Content-Type:application/json' -d @<query_json_file> ` please let me know what is the outcome.

Looks like you are using Old hive CLI driver called Hive1, you need to use Hive2 interactive via Beeline command line on the box it self or via JDBC. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_hive-performance-tuning/content/ch_hive_llap.html https://community.hortonworks.com/articles/4103/hiveserver2-jdbc-connection-url-examples.html

Apr 14 at 09:30 PM Thanks for reporting this. seems like an issue with the packaging on Centos7. We are working on fixing it. In the meantime, can you try with changing the superset database type to 'mysql' or 'postgresql' ? I verified that it works with mysql.
