Subject A Mapreduce job failed. Need Help!
Date Wed, 09 Mar 2016 19:05:40 GMT

Dear Hadoop users:

I followed theinstructions of “Build and Install Hadoop 2.x or newer on Windows” and was
ableto build and install Hadoop 2.7.2 on a PC running Windowns10. 
Then, I tried to runa wordcount job on a single node environment, but this mapreduce job failed.
Couldsomeone please give me any feedback about my case? Do you have any ideas of whyI am failing?
If you needmore information, I would be glad to send you!
Thank youfor your help in advance!
Here is somerelevant information:
