ACCEPTED: waiting for AM container to be allocated, launched and register with RM.

问题

I am working on hadoop2.7.0 single node cluster with 4GB Ram and 40 GB HDD. While executing a word count example on Map reduce , it stopped after Running job...I've tried increasing the memory for container in yarn-site but still no luck.

Error
