Connecting to CDP Public Cloud Data Hub Hive from HDP/CDH Host

Steps to connect from Legacy Cluster to CDP Public Cloud Hive:

1. Build a connection string as follows using Hive Server Endpoint from DataHub by just adding the sslTrustStore and trustStorePassword along with workload username and password for PAM authentication.

   jdbc:hive2://master0.repro.cloudera/default;transportMode=http;httpPath=new/cdp-proxy-api/hive;ssl=true;sslTrustStore=gateway-client-trust.jks;trustStorePassword=*****;user=chella;

2. Get the JKS file downloaded from CDP Knox (Token Integration) and copy it to HDP/CDH host.
3. Get the latest JDBC jar "hive-jdbc-3.1.0-SNAPSHOT-standalone.jar" from CDW.
   
   CDP Control Plane > Management Console > Data Warehouse > click the 3 dots from any of Hive VW and "Download JDBC JAR"
4. Copy the jar "hive-jdbc-3.1.0-SNAPSHOT-standalone.jar"  to HDP/CDH host.
5. Get into beeline from HDP/CDH host
6. Add the jar using the following command

   Beeline version 3.1.0.3.1.5.26-1 by Apache Hive 
   0: jdbc:hive2://c1544-node2> !addlocaldriverjar /root/hive-jdbc-3.1.0-SNAPSHOT-standalone.jar
   
   scan complete in 22ms

7. Connect using the string we built in step [1]

   0: jdbc:hive2://c1544-node2> !connect jdbc:hive2://master0.repro.cloudera/default;transportMode=http;httpPath=new/cdp-proxy-api/hive;ssl=true;sslTrustStore=gateway-client-trust.jks;trustStorePassword=*****;user=chella;
