I am trying to run one example MR job on my pseudo distributed cluster in virtualbox VM (RHEL 6.5, 8GB RAM, 100GB HDD) but after submission of the job It stucks there only.
INFO: mapreduce.Job: Running job: job_1437483993_001
The application tracking url (http://localhost:8088/cluster/applicationID) shows the result like this:
User: root
Name : grep-search
Application-Type : mapreduce
Status : Accepted
FinalStatus : Undefined
What I have tried:
- modified yarn-site.xml and mapred-site.xml for minimum and maximum allocation for memory following the tutorial (http://hortonworks.com/blog/how-to-plan-and-configure-yarn-in-hdp-2-0/)
- ensured that disk space is free enough to accomodate new jobs.
jpsshows all the services are running properly.
But no luck. Please guide me through.
Edit: Here's the log:
