             Summary: Owner should be able to set xattr if not already set.
                 Key: HDFS-13035
                 URL: https://issues.apache.org/jira/browse/HDFS-13035
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs, namenode
            Reporter: Rushabh S Shah


Motivation: This is needed to support encryption zones on WebhdfsFileSystem.

For writing into EZ directory, webhdfs client will encrypt data on client side and will always write into /.reserved/raw/ directory so that datanode will not encrypt since its writing to /.reserved/raw directory.

But then we have to somehow set crypto related x-attrs on the file.

Currently only super user is allowed to set x-attrs.
So I am proposing that the file owner(and superuser) should be allowed to set crypto related x-attrs if they are already not set.
