> 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
> Attachments: HIVE-13817.1.patch, HIVE-13817.2.patch,
> HIVE-13817.3.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> 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.
