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.
> HDFS permissions guide documentation states incorrect default group mapping
> class.
