Subject Re: [jira] Moved: (MAPREDUCE-2008) write Junit test cases that run the Hadoop examples
Date Sun, 05 Sep 2010 21:52:02 GMT
Eli,
Thanks for the heads up, I'll build from the command line and verify that this works.  As
far as these unit tests take a look at the project suggestions page for hadoop, this task
has to do with taking all of the examples and creating junit tests to drive the examples,
 so essentially what I've done is to create a junit test suite that runs each of the examples
as a separate junit test.  What I wanted to know now is whether to create a separate ant target
or leverage and add to one of the pre-existing ant test targets.

It seems that whenever I go to run the test or the test-core target on the mapreduce codebase
they both fail, I did a fresh sync prior to running these targets today.  Am I missing some
other files that are necessary?2) If I want to add a target for compiling and running a junit
test suite that runs all of the current mapreduce examples should I create a brand new target
or try to hack the test target to also run this set of tests, is there a standard when introducing
a new set of tests?Looking forward to getting some more help on the above.Regards

I'll be adding a test suite that tests everything under the src/examples/org/apache/hadoop/examples
package.  Since this is my first contribution to the project I'll need some help to figure
out how to submit this
