Hi [~dimaspivak], mind I take this one? I had another Throttle flakey test to 
take a look and this is related, thanks.

> Seeing this once every month or two in-house. Looks like it's a timing-based 
> test, which makes it prone to flakiness, but I've noticed that whenever it 
> fails, it fails with the same {{AssertionError}} (including values), so it'd 
> be worth digging into. In our case:
> {noformat}
> expected:<1000> but was:<999>
> Stack Trace:
> java.lang.AssertionError: expected:<1000> but was:<999>
>         at 
> org.apache.hadoop.hbase.quotas.TestRateLimiter.testOverconsumptionFixedIntervalRefillStrategy(TestRateLimiter.java:119)
> {noformat}
