---------------------------------
Summary: Selective Group Cache Refresh
Key: HADOOP-11299
URL: https://issues.apache.org/jira/browse/HADOOP-11299
Project: Hadoop Common
Issue Type: New Feature
Reporter: Chris Li
Assignee: Chris Li
Priority: Minor
Currently groups can be refreshed via dfsadmin -refreshUserToGroupMappings, but
this places an undue stress on LDAP if we clear everything at once, where we
may only want to refresh a single user.
This feature would allow the admin to specify a list of users to refresh.
Passing arguments is a feature of HADOOP-10376
