Mapreduce job getting stuck

Question

I am new to hadoop. I have installed cloudera hadoop using cloudera manager on ubuntu 12.04. when I tried testing my installation using command given under "testing the installation" documentation of cloudera my mapreduce job gets stuck at accepted stage and never proceeds from there. I have to kill job. Here is the command i am using:

sudo -u hdfs hadoop jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 10 1

In hue job browser, status of the job is accepted.

Any kind of help will be appreciated.

Thanks in advance.

I had also face same issue while running wordCount problem in pseudo distributed mode, the reason i figured out that my hard drive was almost full because of that i was facing this issue. Try cleaning your hard drive. It will solve your problem.
