Michael Stack resolved HBASE-24131.
-----------------------------------
Fix Version/s: 2.3.0
3.0.0
Hadoop Flags: Reviewed
Assignee: Michael Stack
Resolution: Fixed
Pushed to branch-2.3+ Thanks [~psomogyi]
Just a note to say that this breakup did not solve the issue I was seeing on my
local run. It later failed around this test . I think the local machine is just
bound up on disk. When lots of parallelism (16cores in this case), a bunch of
tests can get hung up on a resource such as disk and backup. A next project is
to study test runs over time resource-wise. Meantime, breaking up bigger tests
into smaller bits -- as long as they still have substance -- is always a good
thing.

> TestExportSnapshot fails fairly regularly locally. Looking, its test timeout.
> Looking at how long it ran, its 13minutes plus. Looking at recent successful
> branch-2 run, it passed but it took about 7-8minutes. Let me break up the
> test into to pieces.
