Few additional checks:
1. On the HiveServer2 host can you check which all ports it has opened and listening to? You can run the following command to findout the ports used.
# netstat -tnlpa | grep `cat /var/run/hive/hive-server.pid`
1(A). Also from any of the Cluster node try to check if you are able to access the HS2 and port 10001 using telnet or netcat to verify any port blocking/network issue? (From beeline run the following command)
# telnet 10.0.0.14 10001
# telnet headnodehost 10001
(OR)
# nc -v 10.0.0.14 10001
# nc -v headnodehost 10001
2. If you are not able to see the port "10001" then then you will need to check the hive configs and the Hive Logs to find out if there are any errors?
3. Also can you double check your Hive Config to find out if it is actually set for "http" mode or "binary" mode in the following property: "hive.server2.transport.mode"
4. In your HS2 connection URL i see that you are missing the "httpPath". Can you please try adding the "httpPath" there something like following and then see if that works? You can find the httpPath value from your HS2 configurations by looking at the property "hive.server2.thrift.http.path"
Example:
# beeline -u "jdbc:hive2://headnodehost:10001/default;transportMode=http;httpPath=cliservice
.
5. For troubleshooting purpose try connecting to beeline in Interactive mode as suggested by @Geoffrey Shelton Okot to verify that you are able to connect to HS2 or not at an alternate option?
Side note:
You can also try to connect the HS2 using the Dynamic discovery mode something as described in the doc: https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.1.0/fault-tolerance/content/dynamic_service_dis...
Ambari UI --> Hive --> Summary (Tab) --> "HiveServer2 JDBC URL" --> Click on the at the right side of the URL to copy the URL and then try this URL with beeline once.
