steve commented on HADOOP-6360:
-------------------------------
Plugin has been working for me, but now all of a sudden I have no Hadoop
options as if the plugin never existed and my HDFS connections are gone?
Plugin is still sitting in my eclipse_home...
When I look in the "Usage Data Collector --> Preview" I see a bunch of these
errors: "Could not acquire children from extension:
org.apache.hadoop.eclipse.views.dfscontent".
Any ideas how to fix this?
> Eclipse Plugin does not build for Hadoop 0.20.1
> -----------------------------------------------
>
> Key: HADOOP-6360
> URL: https://issues.apache.org/jira/browse/HADOOP-6360
> Project: Hadoop Common
> Issue Type: Bug
> Components: contrib/eclipse-plugin
> Affects Versions: 0.20.1
> Environment: SLES 10, Mac OS/X 10.5.8
> Reporter: Stephen Watt
> Attachments: hadoop-0.20.1-eclipse-plugin.jar
>
>
> 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:
> import
> org.eclipse.jdt.internal.debug.ui.launcher.JavaApplicationLaunchShortcut;
> and fails
> 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.
