Subject Secure hadoop and group permission on HDFS
Date Mon, 08 Oct 2012 21:00:46 GMT
With secure hadoop the user name is authenticated by the kerberos server.
But what about the groups that the user is a member of? Are these simple
the groups that the user is a member of on the namenode machine?
Is it viable to manage access to files on HDFS using groups on a secure
hadoop cluster?
