----------------------------------

             Summary: Allow DNS CNAME ALIAS Resolution from apache hive beeline JDBC URL to allow for failover
                 Key: HIVE-13817
                 URL: https://issues.apache.org/jira/browse/HIVE-13817
             Project: Hive
          Issue Type: New Feature
          Components: Beeline
    Affects Versions: 1.2.1
            Reporter: Vijay Singh


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.
