Lab DEV 301 1.1 -- How do you correctly execute the wordcount command?

Hello.

I am following a nearly identical path to another member, Sim _ , who had difficulty with the DEV 301 Exercise 1.1. See: Lab Dev 301 Exercise 1.1 Not a Valid JAR

 

Difference one, my sandbox is on Windows 8.1 whereas his was on OS X.

Difference two, my Hadoop version is 2.7.0, whereas his was 2.5.1.

 

I did steps 1, 2, and 3 without difficulty, checking each step.

Step 4.

$ hadoop jar /opt/mapr/hadoop/hadoop-2.7.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.0-mapr-1506.jar wordcount /user/user01/1.1/IN1 /user/user01/1.1/OUT1

 

After executing this command, I get error messages similar to SIM's and no OUT1 directory, no part-r-00000 file.

 

Question 1, how to correctly execute the wordcount command.

Question 2, how to copy the error messages from his sandbox to this forum, as SIM did.

 

Thank you,

John
