Fix Version/s: None
SLES 10, Mac OS/X 10.5.8
Release Note:This resolves the open issues with the Hadoop eclipse plugin for Eclipse 3.4 and 3.5
When trying to run the build script for the Eclipse Plugin in src/contrib/eclipse-plugin there are several errors a user receives. The first error is that the eclipse.home is not set. This is easily remedied by adding a value for eclipse.home in the build.properties file in the eclipse-plugin directory.
The script then states it cannot compile org.apache.hadoop.eclipse.launch.HadoopApplicationLaunchShortcut because it cannot resolve JavaApplicationLaunchShortcut on line 35:
I believe this is because there is no jar in the eclipse.home/plugins that has this class in that package. I did however find it in org.eclipse.jdt.debug.ui.launchConfigurations.JavaApplicationLaunchShortcut which was inside in org.eclipse.jdt.debug.ui_3.4.1.v20090811_r351.jar in the plugins dir of Eclipse 3.5
Changing the import in the class in the source to the latter allows the build to complete successfully. The M/R Perspective opens and works on my SLES 10 Linux environment but not on my Macbook Pro. Both are running Eclipse 3.5.
To users wanting to do the same, I built this inside Eclipse. To do that I added org.eclipse.jdt.debug.ui_3.4.1.v20090811_r351.jar and hadoop-0.20.1-core.jar to the ant runtime configuration classpath. I also had to set the version value=0.20.1 in the build.properties. You will also need to copy hadoop-0.20.1-core.jar to hadoop.home/build and commons-cli-1.2.jar to hadoop.home/build/ivy/lib/Hadoop/common.
