Brahma Reddy Battula commented on YARN-998:
-------------------------------------------
calling {{rm.drainEvents();}} after registerNode should be fine I think..
{code}
try {
// register the same node third time, this time the register resource
// should work.
rm.registerNode("h1:1234", 8192, 8);
rm.drainEvents();
} catch (Exception ex) {
fail("Should not get any exceptions");
}
{code}
> Keep NM resource updated through dynamic resource config for RM/NM restart
