Can you check whether the name node is running, because it seems to fail to connect to the name node?

Check if Namenode process is running?

ps -ef|grep -i namenode

Then validate if it is listening on 8020 port by running netstat command?

netstat -tulapn|grep 8020

The ATSv2 expects a JSON file in hdfs://{servername}:8020/user/yarn/.yarn/services/ats-hbase/ats-hbase.json

So that need the name node to be running
