Hello,
I am not able to connect to beeline. It is throwing error as "connection refused". I was able to see hive server2 service and hive metastore service is up and running through ambari UI. I am using the below command to connect
beeline -u 'jdbc:hive2://headnodehost:10001/;transportMode=http'
below is the error:

Please could you try this different approach, invoke the beeline as user hive
$ beeline Beeline version 0.14.0.2.2.7.1-10 by Apache Hive beeline> !connect jdbc:hive2://headnodehost:10001/;transportMode=http admin
Hope that helps

Hi Geoff, it is asking password to enter while I am using 'beeline> !connect jdbc:hive2://headnodehost:10001/;transportMode=http admin'
Does this have different password

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.

Thank you. I completed step 1. (netstat -tnlpa | grep `cat /var/run/hive/hive-server.pid`) but could not find 10001. Trying to figure out the logs. Appreciate if you can share me the location of logs( hive configs and the Hive Logs). Also I was ale to connect through beeline 5 days back but not it is not letting me.

Also tried this step (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.) but it is showing no such file or directory found

For 1(a) this is the response " Unable to connect to remote host: Connection refused"

Thank you Geoff. Beeline command not found is the error.

@Nani Bigdata
Please can you share the screenshot of the command line snippet
