Hi, Can you check yarn application logs and check whether AM was started ?
I think you need to set yarn.app.mapreduce.am.env, mapreduce.map.env, mapreduce.reduce.env and yarn.app.mapreduce.am.admin.user.env in your mapred-site.xml file. I too faced this issue a couple of days back, after setting this configurations the issue resolved to me.
