Problem with CompositeGroupMapping

New Contributor


I am managing a CDH 6.2 Cluster with Cloudera Manager.
I was implementing a Composite Group Mapping with:

  • ShellBasedUnixGroupsMapping
  • LdapGroupsMapping

The configuration is as follows:    shellprovider, adprovider    true    server    user . . .    ****    DC=. . .


But when I run the command

hdfs groups


I get the following error:

ERROR security.CompositeGroupsMapping: The mapping provider, adprovider does not have a valid class


What could be the reason for the failure?
