> By default, we query SYSTEM.TASK after an initial delay of 10 seconds. If the
> test setup takes more than 10 seconds, the query on SYSTEM.TASK executes and
> that messes up some of the metadata cache metrics because the test metrics
> don't account for that query. We are seeing this lately because in 5.3 we are
> creating more system tables related to CDC streams. On the PHOENIX-7562
> feature branch we are hitting this often because there we have added another
> system table.
> An easy way to repro this is to add a Thread.sleep > 10 seconds in the
> failing test right before the assert check that is failing.
