NFSGateway fails to start on Centos7 (RU testing)

Testing rolling upgrade from HDP-2.5.3 to 2.5.6-37, the attached error message appears. Retry button did not help, error message returned. Same error when trying to downgrade. Also tried to Pause downgrade and restart NFSGateway on the HDFS service screen, which also fails. Resuming downgrade, ignoring failure: leaves me with alerts in HDFS. Restarting the whole HDFS: alerts still there.
