Subject [jira] [Updated] (HDFS-6664) HDFS permissions guide documentation states incorrect default group mapping class.
Date Mon, 11 Aug 2014 02:02:12 GMT

     [ https://issues.apache.org/jira/browse/HDFS-6664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ray Chiang updated HDFS-6664:
-----------------------------

    Attachment: HDFS6664-01.patch

Mostly a cut-and-paste from core-default.xml, which has some very good descriptive text for
the org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback implementation behavior.

Let me know how it looks to you.

> The HDFS permissions guide states that our default group mapping class is {{org.apache.hadoop.security.ShellBasedUnixGroupsMapping}}.
 This is no longer true.  The default has been changed to {{org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback}}.
