stack commented on HBASE-6201:
------------------------------
Thanks for doing this Enis. +1 on making subjiras off this one.
On IT tests and mvn verify, I concluded it a lost cause. Maybe you can figure
how to make it change its behavior when you pass a -Dconf=xxxx and have it
instead run on a real cluster (I found the mvn verify targets insufficient
IIRC).
The above is a comment on the mvn verify mechanism only, not on the intent of
this issue. I'm rah-rah on your intent. Just suggesting we may need to do it
atop a different vehicle (BT would be coolio. On hearing BT perspective on
this, we may have blown that for a while. We've gotten Roman excited on
multiple occasions but have failed to come through. I'd say lets deliver
something first, then Roman might think us serious this time).
bq. We need a tool on top of MiniHBaseCluster or improve HBaseTestingUtility,
so that tests can interface with the mini cluster or the actual cluster
uniformly.
I agree. Need to make it so test is same whether on mini or real cluster.
+1 on #3 and #4 points above.

> Key: HBASE-6201
> URL: https://issues.apache.org/jira/browse/HBASE-6201
> Project: HBase
> Issue Type: Bug
> Components: test
> Affects Versions: 0.96.0
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
>
> Integration and general system tests have been discussed previously, and the
> conclusion is that we need to unify how we do "release candidate" testing
> (HBASE-6091).
> In this issue, I would like to discuss and agree on a general plan, and open
> subtickets for execution so that we can carry out most of the tests in
> HBASE-6091 automatically.
> Initially, here is what I have in mind:
> 1. Create hbase-it (or hbase-tests) containing forward port of HBASE-4454
> (without any tests). This will allow integration test to be run with
> {code}
> mvn verify
> {code}
> 2. Add ability to run all integration/system tests on a given cluster. Smt
> like:
> {code}
> mvn verify -Dconf=/etc/hbase/conf/
> {code}
> should run the test suite on the given cluster. (Right now we can launch some
> of the tests (TestAcidGuarantees) from command line). Most of the system
> tests will be client side, and interface with the cluster through public
> APIs. We need a tool on top of MiniHBaseCluster or improve
> HBaseTestingUtility, so that tests can interface with the mini cluster or the
> actual cluster uniformly.
> 3. Port candidate unit tests to the integration tests module. Some of the
> candidates are:
> - TestAcidGuarantees / TestAtomicOperation
> - TestRegionBalancing (HBASE-6053)
> - TestFullLogReconstruction
> - TestMasterFailover
> - TestImportExport
> - TestMultiVersions / TestKeepDeletes
> - TestFromClientSide
> - TestShell and src/test/ruby
> - TestRollingRestart
> - Test**OnCluster
> - Balancer tests
> These tests should continue to be run as unit tests w/o any change in
> semantics. However, given an actual cluster, they should use that, instead of
> spinning a mini cluster.
> 4. Add more tests, especially, long running ingestion tests (goraci, BigTop's
> TestLoadAndVerify, LoadTestTool), and chaos monkey style fault tests.
> All suggestions welcome.
