Naganarasimha G R updated YARN-4654:
------------------------------------
Attachment: YARN-4654.v1.003.patch
Had an offline discussion with [~rohithsharma] and he was of the opinion that
test case should fail when the modifications in *RMAdminCLI* is not present
which was not happening in the patch. IIUC issue was not actually throwing a
exception but intended behavior was not happening hence modified the test code
to differ the behavior of CommonNodeLabelsManager when invalid NodeId is sent.
> Yarn node label CLI should parse "=" correctly when trying to remove all
> labels on a node

> Currently, when adding labels to nodes, user can run:
> {{yarn rmadmin -replaceLabelsOnNode "host1=x host2=y"}}
> However, when removing labels from a node, user has to run:
> {{yarn rmadmin -replaceLabelsOnNode "host1 host2"}}
> Instead of:
> {{yarn rmadmin -replaceLabelsOnNode "host1= host2="}}
> We should handle both of "=" exists/not-exists case when removing labels on a
> node.
