You probably need more memory.
Understand that in order to do anything remotely useful Hadoop needs a
lot of memory. Just to run the terasort benchmark, my cluster's worker

Since installation. I am not clear with what to do to fix this.
I have been searching on various forums from past 2-3 months about this.
I had installed hadoop on a Ubuntu virtual machine as per instructions
available in README file in sources folder every thing went fine there
were some errors at the end I am getting a low memory message.
Here is a screenshot for the same.
