How do you clean up the Eclipse MapReduce plugin?

Question

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

I cannot return the eclipse to its pure previous state - I am tempted to just start with a new eclipse installation, but it will be a lot of work (installing other plugins like git and pydev plus re-creating the workspace). So how do you clean up the Eclipse MapReduce plugin?

Alternatively: how to get a properly installed eclipse hadoop plugin connected to a local tasktracker and developing HDFS for hadoop 0.18.3?

Answer 1

there is no way to remove, you just remove hasoop-eclipse-plugin.jar from the plugins folder in eclipse and update eclipse.
