无法启动NFS网关-Hadoop

我无法在Cloudera中启动NFS网关。它给我错误Supervisor returned FATAL. Please check the role log file, stderr, or stdout

但是我可以在stdout中观察到的唯一奇怪的事情是

socket.error: [Errno 111] Connection refused
+ '[' 1 -ne 0 ']'
+ echo 'Cannot connect to port 111.'
+ return 1
+ '[' 1 -eq 1 ']'
+ echo 'No portmap or rpcbind service is running on this host. Please start portmap or rpcbind service before attempting to start the NFS Gateway role on this host.'
+ exit 1

我试图将端口111更改为1111，但这没有帮助。有什么想法我该怎么办？
