A Mapreduce job failed. Need Help!

[Juri Yanase Triantaphyllou <ju...@aol.com>]

Dear Hadoop users:


I followed the instructions of “Build and Install Hadoop 2.x or newer on Windows” and was able to build and install Hadoop 2.7.2 on a PC running Windowns10. 
Then, I tried to run a wordcount job on a single node environment, but this mapreduce job failed. Could someone please give me any feedback about my case? Do you have any ideas of why I am failing?
 
If you need more information, I would be glad to send you!
Thank you for your help in advance!
