[~Karthik Palaniappan],  thanks for reporting this, it's better to return a 
better exception and error msg to user if there is no {{newLength}}.
This can be done by checking whether newLength is null string 
(NewLengthParam#DEFAULT) in {{NamenodeWebHdfsMethods}}, feel free to upload a 
patch to fix it.

In the document, the newLength is already a required parameter, for any 
optional parameter, there is []
