> HADOOP-11934 discovered an infinite loop of dependencies in the use of credential provider in LdapGroupsMapping. It added a new localjceks:// URI to workaround the problem. The assumption is that the groups mapping is used only in NameNode and that using a local credential file is not a problem.
> However, there are cases where Hadoop clients, such as Sqoop, may use hdfs:// based credential provider and use LdapGroupsMapping at the same time. We should use HADOOP-12846 to exclude hdfs:// URI credential providers.
