As the error is basically "Connection Refused"

jdbc:hive2://xxx.yyy.com:10000/default java.net.ConnectException: Connection refused (Connection refused) (state=08S01,code=0)

So can you please check if the Port 10000 is opened on the HS2 host?

# netstat -tnlpa | grep 10000

.

Also please check if the port 10000 is accessible from the host where you are Spark2 is installed. This is to isolate any Connectivity / Firewall issue:

# nc -v xxx.yyy.com 10000
(OR)
# telnet xxx.yyy.com 10000

.
