title: Error while trying to run Spark
body: <p>I am new to spark. I have downloaded the spark version 1.3.1 prebuilt for hadoop version 2.6 . I extracted and navigated to the folder and typed in the below command :
    ./bin/spark-shell
  for which i get an error which says spark-shell command not found. I did the same on windows using git bash for which I get an error saying </p>
  
  <p>spark-submit : line 26 tput command not found</p>
  
  <p>is there something else I need to do before trying to run spark?</p>
