Yufei Gu commented on YARN-4907:
--------------------------------
Some {{waitForState}} return a boolean since the caller need to assert on
different value. Some {{waitForState}} doesn't since the caller expect them to
assert if the state is reached before timeout. So it makes sense to have both.
I changed all {{System.out.println}} to {{LOG.info}} and make sure every wait
has a timeout.
> Make all MockRM#waitForState consistent.

> There are some inconsistencies among these {{waitForState}} in {{MockRM}}:
> 1. Some {{waitForState}} return a boolean while others don't.
> 2. Some {{waitForState}} don't have a timeout, they can wait for ever.
> 3. Some {{waitForState}} use LOG.info and others use {{System.out.println}}
> to print messages.
