nkeywal commented on HBASE-7243:
--------------------------------
Yep, 1 region server should be fast enough.
I think you could do the test with 1000 regions: it should push the system
enough while being reliable in the results shown.
To determine the max time, I think there is no other way than trying and then
add a 50% security. To lower variance, I personally use a ramdisk, but it's not
something easy to generalize...
You can set a timeout in junit btw: @Test(timeout=10000)
This patch will be very useful to detect errors sooner (and before go live :-)

> After HBASE-7220, I think it will be good to write a unit test/IT to create a
> large number of regions. We can put a reasonable timeout to the test.
