Lars Hofhansl commented on HBASE-7455:

Whoa, that's not good. In trunk? Compaction concurrent with droptable?

> When I measure the times in TestReplication.queueFailover, it takes about 15s on my (reasonably
fast) Laptop.
> The timeout in queueFailover currently is 1500*2*15 = 45000ms.
> For setup before each test (which truncates the table and waits for the changes to replicate)
it is 1500*15 = 22500ms.
> Interestingly I see queueFailover failures where the wait time is measured as 64260ms
and some at 72316ms.
> Since these numbers are not even close to 45000ms, the machine or JVM must have been
stuck for 15 or almost 30s (otherwise we'd get a timeout and the total time spent should be
close to the timeout).
> So I would suggest that we increase the timeouts further.
> We could set SLEEP_TIME to 2000 and retries to 20. Would lead to 2000*2*20 = 80000ms.
> Any objections?
