> Configuration keys in Kerberos descriptors should allow for variable
> replacement. For example a typical {{configurations}} block may look like
> {code}
> "configurations" : [
> "core-site": {
> "hadoop.proxyuser.hive.groups":"${hadoop-env/proxyuser_group}"
> },
> "hive-site": {
> .....
> },
> "webhcat-site": {
> ....
> }
> ]
> {code}
> However some configuration keys need to be dynamically generated and should
> be generated using the existing variable replacement feature in
> {{org.apache.ambari.server.state.kerberos.AbstractKerberosDescriptor}}. For
> example:
> {code}
> "configurations": [
> "core-site": {
>
> "hadoop.proxyuser.${hive-env/hive_user}.groups":"${hadoop-env/proxyuser_group}"
> },
> "hive-site": {
> .....
> },
> "webhcat-site": {
> ....
> }
> ]
> {code}
> The configuration key {{hadoop.proxyuser.$\{hive-env/hive_user\}.groups}}
> should be processed such that _$\{hive-env/hive_user\}_ is replaced some
> value like {{hive}} to yield {{hadoop.proxyuser.hive.groups}}
