How do you cleanly uninstall the Eclipse MapReduce plugin?

Question

I'm trying to get the eclipse plugin for hadoop development to work, I'm using hadoop 0.18.3. I installed the old MapReduce plugin (http://www.alphaworks.ibm.com/tech/mapreducetools) on Eclipse v3.5.2 (M20100211-1343) by copying it to /Applications/eclipse/plugins and restarting eclipse but that didn't work, I figured it was because it was developed for older versions of hadoop and eclipse (circa 2007). Then I realized that the hadoop distribution has a jar under contrib/eclipse-plugin - so copied that to /Application/eclipse/plugins and restarted... then things got funky. So I tried to remove them both so I could start over but that fails, when I go to 'Window -> Open Perspective -> Other' there's a "ghost" of the old plugin ... no icon, it just says '' (literally surrounded by angle brackets).

I can't seem to revert eclipse to a clean prior state - I'm tempted to just start over with a fresh eclipse install but that'd be a lot of work (installing other plugins like git and pydev plus re-creating the workspace). So how do you cleanly uninstall the Eclipse MapReduce plugin?

Alternatively: how do I get the eclipse hadoop plugin properly installed, connected to the local tasktracker and development HDFS for hadoop 0.18.3?

Answer 1

there is no way on uninstalling , you just delete the hadoop-eclipse-plugin.jar from the plugins folder in eclipse and refresh eclipse.
