[jira] [Comment Edited] (HADOOP-10701) NFS should not validate the
access premission only based on the user's primary group
[ https://issues.apache.org/jira/browse/HADOOP-10701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14036268#comment-14036268 ]

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 similar as those in IdUserGroup, which has a mapping cache already.
