Description

Oozie GroupsService wraps Hadoop user groups mapping to get groups for user, which requires to reference Hadoop configurations, especially the properties related to groups mapping provider (such as LdapGroupsMapping).

To avoid replication of such configurations into oozie-site.xml, mechanism is needed to configure the Hadoop configurations folder (often mentioned hadoop-conf) for the service, as HadoopAccessorService currently does.

Such work can be done per Service, as HadoopAccessorService, but would it be better to avoid code changes or similar work when other Service also needs to do that in future.
