@Liana Napalkova Can you please share the complete StackTrace of the "error with HiveServer2" Also can you please check on the HiveServer2 host to know if hive thrift port 10000 is actually opened or not? # netstat -tnlpa | grep 10000 .

Also if possible then can you also check if you are able to start the Hive Components manually or not ?
