Just standard box like yours (ubuntu). I suspect something must be
wrong. Could you determine which tests take long time. On hudson, it
seems that tests take 1:30 on average.

Hi,
I am aware of HowToContrib wiki page but in my case [ant test] takes more
then one hour. I can not tell you how much time it takes because I always
stopped it after 4-5 hours...
I was running these test on notebook Dell, dual core 1GB of RAM, Windows XP.
I haven't tried it now after switching to Ubuntu but I think this should not
make a big difference. What kind of HW are you using for Hadoop testing? I
would definitely appreciate if [ant test] runs under an hour.

Lukas

Hi,
How long is Hadoop full unit test suit expected to run?
How do you go about running Hadoop tests? I found that it can take hours
for
[ant test] target to run which does not seem to be very efficient for
development.
Is there anything I can do to speed up tests (like running Hadoop in a
real
cluster)?
Hi,
Yes, ant test can take up to an hour. On my machine it completes in less
than an hour. Previously work has been done to reduce the time that tests
take, but some of the tests take a long time by nature such as testing dfs
balance, etc.
There is an issue to implement ant test-core as a mapred job so that it can
be submitted to a cluster. That would help a lot.
Say I would like to fix a bug in Hadoop in ABC.java. Is it OK if I execute
just ABCTest.java (if available) for the development phase before the
patch
is attached to JIRA ticket? I don't expect the answer to this question is
positive but I can not think of better workaround for now...
This very much depends on the patch. If you are "convinced" by running
TestABC, that the patch would be OK, then you can go ahead and submit patch
to hudson for QA testing. However, since the resources at Hudson is limited,
please do not use it for "regular" tests. As a side note, please run ant
test-patch to check your patch.
