Description

This is a minor issue because the uuid is ultimately displayed.

Issuing 'kudu fs dump uuid ...' gives a permission denied error as shown below. Testing against the Kudu demo VM yielded the same result. Using sudo gives a different error.

My session below shows results of using plain kudu command, followed by an attempt to clear the permission denied message by using sudo:

[training@localhost ~]$ kudu fs dump uuid -fs_wal_dir /var/lib/kudu/master -fs_data_dirs /var/lib/kudu/master
