[HIVE-13817] Allow DNS CNAME ALIAS Resolution from apache hive beeline JDBC URL to allow for failover

• Type: New Feature
• Status: Resolved
• Priority: Major
• Resolution: Duplicate
• Affects Version/s: 1.2.1
• Component/s: Beeline
• Target Version/s: 1.3.0
• Release Note: Hive JDBC driver is modified to support use of canonical name in environments where CNAME alias is used infront of DR cluster switch. The _HOST part of principal should take care of principal name changes as long as VIP points to Load balancer A Record.

Description

Currently, in case of BDR clusters, DNS CNAME alias based connections fail. As _HOST resolves to exact endpoint specified in connection string and that may not be intended SPN for kerberos based on reverse DNS lookup. Consequently this JIRA proposes that client specific setting be used to resolv _HOST from CNAME DNS alias to A record entry on the fly in beeline.
