I am trying to get a job to run on the Hadoop cluster but they are stuck in accepted. The problem is that, even if I have two nodes the resource manager cannot see it. In fact, in the web UI I don't see any resources nor nodes:
Resource manager doesn't have any warnings or error in the log file and when I start a job it says this:
(base) ubuntu@myipaddress:~$ hadoop jar $YARN_EXAMPLES/hadoop-mapreduce-examples-3.3.1.jar wordcount /user/ubuntu/wordcount/input /user/ubuntu/wordcount/output

And then it is obviously stuck.
I thought that maybe my nodes weren't connected, but when I do hdfs dfsadmin -report everything is there and works normally.
I have no idea what to do, any clue? Thank you very much
