>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: security
>    Affects Versions: 2.6.0
>            Reporter: Wei-Chiu Chuang

>         Attachments: HADOOP-13548.001.patch, HADOOP-13548.002.patch
> 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.
