Yep, that was it (the extra CLASSPATH folders in the run configuration
templates). Thanks!

Kirk,
IIRC, the "ant eclipse" target also bundles in some pre-configured Run
Configurations into your Eclipse (You can see them in the
Run-Configurations drop down as "SpecificTestTemplate" or so). Using
that template should get rid of a lot of issues.
(Btw, running specific tests from ant is possible too, via
-Dtestcase=Name/Pattern)

Hi all,
I'm trying to run some of the unit tests within Eclipse. But with a fresh
checkout of the HDFS source, unit tests that use webapps generate errors in
Eclipse.
Steps to reproduce:
1. Get source
1. cd /tmp
2. mkdir test
3. cd test
4. git clone https://github.com/apache/hadoop-hdfs.git
5. cd hadoop-hdfs
2. Set up Eclipse project
1. Run `ant eclipse`
2. Run Eclipse with /tmp/test as the workspace
3. File -> Import...
4. Import "General" -> "Existing Projects into Workspace",
click "Next"
5. Select root directory "/tmp/test", select "hadoop-hdfs" and
click "Finish"
3. Navigate to "TestBlockRecovery" test source and select "Run As..."
"JUnit Test"
I expected it to pass, but instead I get this error:

I'm assuming that it's an issue with the Eclipse project generation, but I
haven't been able to solve it by manually hacking the .classpath Eclipse
file.
Any ideas?
Thanks,
Kirk
