I am trying to connect with the HiveServer2 with the use of dplyr.spark.hive package but I am occuring an error that I can not pass a username to the dbConnect function and probably this is the reason I receive an error about NULL client_protocol.
Does anyone know how to fix this or how to pass user/username to the dbConnect function, where the driver is a JDBC?
This beeline request works fine for me
beeline -u "jdbc:hive2://host:port/dbname;auth=noSasl" -n mkosinski --outputformat=tsv --incremental=true -f sql_statement.sql > sql_output
but this R equivalent does not:

EDIT 1
I've tried to use different .jar for connection (as suggested in comments) and it looks like the previous problem is solved (I probably used wrong .jar) but now I receive an error telling me that the connection is somehow not configured:
