Nick Dimiduk commented on HBASE-7243:
-------------------------------------

Reducing this to a single regionserver with 1000 regions allows this test to 
execute within the memory constrains already imposed by the hbase-it/pom.xml. 
It completes pretty consistently in 150-200 secs on my laptop (no ramdisk).

Using the @Test(timeout=...) feature is appealing because it simplifies the 
test logic considerably. However, only constant expressions are accepted as 
arguments to the @Test annotation. That means this setting cannot be altered by 
a local administrator who is also interested in tweaking the other values. For 
this reason, I'll retain the existing timer logic -- that is, unless there's a 
strong desire to remove configurability in general from this patch.

> 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.
