Subject [jira] [Updated] (HADOOP-14370) GroupMapping implementation in Groups.java is not same as core-default.xml
Date Tue, 02 May 2017 03:43:04 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14370?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

xuekang updated HADOOP-14370:
-----------------------------
    Description: 
In hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/Groups.java,
the default GroupMappingServiceProvider is ShellBasedUnixGroupsMapping.class,  but in core-default.xml,
the value of hadoop.security.group.mapping is org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback。

It is misleading.
