impala customize group mapping service


Currently, we are running impala 2.7, and we enable impala with sentry service.

One problem is that, whenever any new user want use impala, we need to create the user account and groups on the linux os across all the nodes that running impalad.


Is their any document that given guide to develop and deploy customize group mapping service plugin on impala?

All the group mapping client suppose to request the same server for user groups, which the server is stored all the user and its groups mapping.
