-[DISCUSSION] How we gonna test apache builds on real HW

This email is essentially an attempt to work out a community consensus
for a process around testing of Hadoop bits on real hardware.
Here are few pre-requisites:
- bits are produced by Jenkins builds (e.g.
- bits are deployable (e.g. a tar ball or else comprised from all
necessary jars, .so, driver scripts, etc.) immediately and require
only minor configuration changes to run them on a hardware
- set of tests (a primitive one for the beginning, more elaborate
later on) to check if a produced build is viable and can do sensible
things when is deployed to a cluster (sort of integration tests, if
At the moment there's a set of static configs (HADOOP-7278) and tiny
deployment script which downloads, unpacks, installs, starts a cluster
on 4 nodes. Script is driven by
job. Successful deploys trigger a test job
which executes some Hadoop examples at the moment.
It is all very quickly put together to have a working validation job
for 0.22 release and I want to limit the scope of this discussion how
we can make a better use of this rather than finding a better solution
for the approach. The latter can be done on JIRA, I think.
Here's a number of questions/answers for the on-cluster testing thing:
- who should receive notifications about failing deployment tests?
Possible answers: specific release's maillist; an RM; a dev. list;
- what information should be included into notification to help
identify potential issues: a piece of commit logs; nothing at all?
- what sets of tests to run. Answers: all hadoop examples, terasort,
pipes, compression jobs, etc.
- how validation failures should be treated? As a blockers (similar
to functional test failures); "good to know but who cares" kinda
I would like to hear your opinions on this topic.
