Hello Aaron,

Thank you for the kind welcome and advice on starting up. 

Happy to say that I completed most of the setup steps without a problem.  The only problem
I got is when I was defining and querying. Please find the lines of the console as follows,

Any idea as to what am doing wrong?

Also, another thing: I tried to open the project on Eclipse (as a Maven project with profile
'binary'), but some of the Hadoop imports show as missing classes. What IDE do you guys use?
If it's Eclipse, am I missing a step in creating the project?

Thanks and Best Regards,
