> Key: HIVE-17489
> URL: https://issues.apache.org/jira/browse/HIVE-17489
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Reporter: Mithun Radhakrishnan
> Assignee: Thiruvel Thirumoolan

>
> 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/mycluster-hcat.blue.myth....@grid.myth.net}}. 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.).
