Ayush Saxena commented on HDFS-14193:
-------------------------------------

The two tests are the ones which were the scenario of fallbacks when default NS 
was not specified.As of now we will not be having any fallback.So we can't get 
them in.There are now 3 scenarios possible now in the present and I think the 
test present covers those three. If you think need of any more scenarios other 
than being covered.Would get them in too. :)

> In the present scenario, if the default nameservice is not explicitly 
> mentioned.Each router fallbacks to it local namespace as Default.There in 
> each router having different default namespaces. Which leads to 
> inconsistencies in operations and even blocks in maintaining a global uniform 
> state. The outputs becomes specific to which router is serving the request 
> and is different with different routers.
