Speed up the test suite
-----------------------
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.
