 Course does not mandate any programming language for writing Hadoop MapReduce jobs; but they have mainly used / taught Hadoop MapReduce jobs using `Python` [i.e. with Hadoop Streaming approach for running jobs] during the course.<br>
 
-I have developed Hadoop MapReduce code for the 2 problem statements [3 questions each] in 2 programming languages; `Python` and `Java`.<br>

-## Instructions for Virtual Machine download / setup
-Please refer [instructions document](IntroductiontoHadoopandMapreduce-VMsetup.doc) provided by Course Instructors for details on the setup required for running these examples.<br>
-As mentioned in the above document, Virtual Machine image with Hadoop installed and preconfigured, can be downloaded from [Udacity website](http://content.udacity-data.com/courses/ud617/Cloudera-Udacity-Training-VM-4.1.1.c.zip). 
+## Instructions for Virtual Machine download and setup
+Please refer [instructions document](IntroductiontoHadoopandMapreduce-VMsetup.doc) provided by Course Instructors for details on the Hadoop Virtual Machine [VM henceforth] setup required for running these examples.<br>
+As mentioned in the above document, VM image with Hadoop installed and preconfigured, can be downloaded from [Udacity CDN](http://content.udacity-data.com/courses/ud617/Cloudera-Udacity-Training-VM-4.1.1.c.zip). 
 
-Please be forewarned, the size of this compressed VM archive is 1.7 GB. And it does not uncompress with either 7-Zip or Windows default Zip utility. Please use WinRAR or WinZip or even Cygwin unzip to uncompress the same, if you are on Windows. On other Operating Systems, probably `unzip` command might work just fine. Uncompressed size of this VM is 4.2 GB.

+Credentials to login to this Virtual Machine are: `training` / `training`. You will not need `root` access for any of the assignments of this Course. But just in case if you need, the password for `root` is `training`.
 
-Please ensure that you configure the VM to at least 1.5 GB of RAM. It might run much better with 2 GB though.
+Please ensure that you configure the VM to at least 1.5 GB of RAM in [VMware Player](https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_player/6_0). It might run much better with 2 GB though. I have used VMware Player v5.0.2, the current latest version as of this writing [i.e. 28th November, 2013] is v6.0.1.

 > *Update at 11/27/2013 10:00:26 PM IST*: Had to remove these input files from the repo as the GitHub Windows client is not able to sync the repo [or rather getting badly stuck with illegitimate alphabets] with these compressed archives.<br>
 
-These input compressed archives can also be downloaded from Udacity servers. Look [here](http://content.udacity-data.com/courses/ud617/purchases.txt.gz) for input file for Problem Statement 1 and [here](http://content.udacity-data.com/courses/ud617/access_log.gz) for Problem Statement 2.<br>
