             Summary: FileSystem object can take a parameter to expose all / 
selected methods
                 Key: HDFS-14248
                 URL: https://issues.apache.org/jira/browse/HDFS-14248
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Tanmoy


Currently, the filesystem api in Hadoop exposes all actions (create, delete, 
append) to users. There are situations where HDFS users (users of the FS api) 
should be allowed to only create/append , but never delete. 

HDFS ACLS does not allow such feature at the filesystem layer. Idea is to block 
cli access for developers. Improve the FileSystem class to take parameters 
while creating the object. If userRole = "Dev" , then don't expose delete 
methods for user.
