Lefty Leverenz commented on HIVE-17489:
---------------------------------------
Thanks for the doc, [~mithun]. I did some minor editing, documented the other
new parameter (*hive.server2.authentication.client.kerberos.principal*), and
added cross-references between them.
Please review and let me know if the cross-references were a good idea or not.
(Does HA mean High Availability?)
* [hive.metastore.client.kerberos.principal |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.client.kerberos.principal]
* [hive.server2.authentication.client.kerberos.principal |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.server2.authentication.client.kerberos.principal]
> Separate client-facing and server-side Kerberos principals, to support HA

> On deployments of the Hive metastore where a farm of servers is fronted by a
> VIP, the hostname of the VIP (e.g. {{mycluster-hcat.blue.myth.net}}) will
> differ from the actual boxen in the farm (.e.g
> {{mycluster-hcat-\[0..3\].blue.myth.net}}).
> Such a deployment messes up Kerberos auth, with principals like
> {{hcat/[email protected]}}. Host-based checks will
> disallow servers behind the VIP from using the VIP's hostname in its
> principal when accessing, say, HDFS.
> The solution would be to decouple the server-side principal (used to access
> other services like HDFS as a client) from the client-facing principal (used
> from Hive-client, BeeLine, etc.).
