MapReduce jobs get stuck in Accepted state

Question

I have my own MapReduce code that I\'m trying to run, but it just stays at Accepted state. I tried running another sample MR job that I\'d run previously and which was succe

Answer 1

A job stuck in accepted state on YARN is usually because of free resources are not enough. You can check it at http://resourcemanager:port/cluster/scheduler:

1. if Memory Used + Memory Reserved >= Memory Total, memory is not enough
2. if VCores Used + VCores Reserved >= VCores Total, VCores is not enough

It may also be limited by parameters such as maxAMShare.
