     [ https://issues.apache.org/jira/browse/HADOOP-13548?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Wei-Chiu Chuang updated HADOOP-13548:
-------------------------------------
    Attachment: HADOOP-13548.002.patch

v02:
Fixed three bugs:
    (1) A TestLdapGroupsMapping test case used jceks://. Changed it to localjceks.
    (2) The ProviderUtils.excludeIncompatibleCredentialProviders had a bug
    identifying correct class corresponds to a scheme.
    (3) LdapGroupsMapping should also exclude user:// scheme.

> 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.
