Possible solution:

1. Recreate Keytabs
2. Start Yarn from CLI and fix Ambari issue

https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.2/bk_command-line-upgrade/content/start-yarn-mr-...

Kindly provide the below output for further investigation.

curl -sS -L -w '%{http_code}' -X GET -d '' -H 'Content-Length: 0' --negotiate -u : 'http://hostname:50070/webhdfs/v1/ats/done?op=GETFILESTATUS
