----------------------------------------
Summary: Remove recursive dependencies of credential providers in
LdapGroupsMapping
Key: HADOOP-13548
URL: https://issues.apache.org/jira/browse/HADOOP-13548
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.6.0
Reporter: Wei-Chiu Chuang
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.
