How to remove a Column Family Property

[Pankaj kr]

Hi,
Suppose I have enabled encryption in a column family by setting "ENCRYPTION => 
'AES'".
Now I want to disable encryption for this column family. How to do this through 
HBase Shell?
As per alter table syntax, at column family level we can add CFs, delete CFs or 
set/modify  properties. How to remove a CFs property?

                Any help would be much appreciated.

Regards,
Pankaj
