Hemanth,


       I didn't know how to fix this problem. Here is what I did - I just
reboot my machine to fix this issue. Right now I get another issue. When I
am trying to run an application by clicking "Run As" -> "Run on Hadoop",
nothing happens visually and something happens in background because I get
an indication when I try to rebuild the project. I can even not kill
eclipse.exe from Windows Task Manager.

java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)

Jim
