I have configured hadoop on windows10. When I try to run WordCount program it doesn't finish the job:

What can I do to fix it?

Note: I have made a little change to the original program; input and output files are compiled with the code and don't need to be provided as arguments.

Open the `url to track the job` listed on the terminal. Go look at YARN – OneCricketeer Mar 01 '17 at 17:14

`waiting for AM container to be allocated`. The ApplicationMaster container cannot be started, so one possibility is memory issues. – OneCricketeer Mar 01 '17 at 17:35
Ok. any solutions for that? – MohammadHossein R Mar 01 '17 at 17:48
I found the problem and it was ridiculous: http://stackoverflow.com/a/28724329/4314810 – MohammadHossein R Mar 01 '17 at 19:24
Well, yeah. HDFS disk space is precious. You should setup Ambari to get metrics to monitor your environment better. – OneCricketeer Mar 01 '17 at 21:48
Take a look at yarn resource manager log to see why app master container could not be allocated. – Weiwei Yang Mar 02 '17 at 14:29
