Subject [jira] [Commented] (HADOOP-10701) NFS should not validate the access premission only based on the user's primary group
Date Wed, 18 Jun 2014 19:56:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14036268#comment-14036268

Brandon Li commented on HADOOP-10701:
-------------------------------------

Thank you, [~qwertymaniac], for the fix. The patch looks nice. What [~PKUKILLA] said makes
sense too. To support the easy deployment in the Cloud, we could provide a config property
to let NFS gateway ignore the GIDs in the request and do a lookup in IdUserGroup, which has
a mapping cache already.

based on the primary Unix group the user is associated with and Secondary Unix groups are
ignored.
