Ayush Saxena commented on HDFS-14156:
-------------------------------------
I guess an implementation in MockResolver would be well enough and it would be
quite helpful too for later stages.Would give us extra liberty to check for
both single and multiple NS in the later stages too.I don't guess for this we
would be needing any critical change in router Conf in the test.
Well Just an ALT.If it has adversities around we will be bound to go with the
new class.But I think the option of disabling MockResolver shouldn't cause any
such trouble as on default that would be turned off only.We will turning to it
only when we need to have the test for Single NS only.
I guess thats pretty much worth a try. :)
