             Summary: Configuration to allow group with read-all privilege
                 Key: HDFS-16164
                 URL: https://issues.apache.org/jira/browse/HDFS-16164
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Leon Gao
            Assignee: Leon Gao


We see more use cases that need read-all permission to hdfs. One example is 
data quality service that needs to read all the data but no need to write. 
Currently seems hdfs only supports supergroup that can do anything.

Maybe we can add configuration like dfs.permissions.read-all.group to manage 
this type of permissions easily.
