Jim Kellerman commented on HBASE-410:
-------------------------------------
I would prefer that we start a MiniDFS at the beginning of the test suite and
just leave it up until the end of the suite. I believe that ant has some kind
of pre and post target processing that it can do.
-1 on running the parts (master, region server, client) in a single thread.
That is not how they are designed to run, and testing them in such a mode is
unrealistic.
Finally, for tests that get hung, reducing the timeout until the test is killed
(15 minutes?) until a more reasonable 5 minutes would speed things along.

> Key: HBASE-410
> URL: https://issues.apache.org/jira/browse/HBASE-410
> Project: Hadoop HBase
> Issue Type: Test
> Components: test
> Reporter: Bryan Duxbury
> Priority: Minor
> Fix For: 0.2.0
>
>
> The test suite takes a long time to run, and a lot of the time spent running
> is really wasted on repeated startup and shutdown, waiting for asynchronous
> events to occur, and production-tuned timeouts to occur. Additionally, we use
> a MiniDFS instead of the local filesystem.
> We should:
> - Make whatever changes are needed to the local DFS so that it can run on
> Windows and use that as the basis of all of our tests
> - Minimize redoing expensive setup where possible by combining tests into
> groups or suites that can share common setup
> - Create a way of running all the parts (Master, Regionserver, Client) in a
> single thread and explicitly advancing through necessary states so that we
> can reliably and quickly get what we need tested accomplished
> - Use smaller test datasets where it would make a difference (TestTableIndex
> and TestTableMapReduce, I'm looking at you!)
> A faster test suite means faster turnaround on new patches, faster Hudson,
> and a shorter patch queue. Not to mention less annoyance on the part of the
> developers.
