@denysobukhov  Based on error stack trace which you have shared looks like the connection is getting closed before fetching the results for the query. Is there a delay between submitting the query and then receiving the error? If yes, what is the delay exactly. During the time of error appears,have you observe any alerts from HS2 ? Are you able to  connect to HS2 from beeline without any issue during the time of  failure? Is hive2host.loc is the loadbalancer URL? We might require the JDBC TRACE LOGS and HS2 logs to determine the cause  of failure. Thank You. ... View more
