解决方案

首先查看error日志，resource_management.core.exceptions.ExecutionFailed: Execution of ‘ambari-sudo.sh su hdfs -l -s /bin/bash -c ‘ulimit -c unlimited ; /usr/hdp/3.1.0.0-78/hadoop/bin/hdfs --config /usr/hdp/3.1.0.0-78/hadoop/conf --daemon start namenode’’ returned 1.查找解决方法无果。
然后仔细查看output日志（上面放的是不完整版），发现java.net.BindException: Port in use: master:50070，首先排查端口是否被占用了：netstat -lnp|grep 50070，如果被占用了杀掉占用进程就可以了：kill -9 <进程号>，但是没有发现占用端口的进程。于是，查看配置信息：vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
39.**.***.128  master # 公网ip
123.**.***.54  slave1
123.**.***.90  slave2
59.**.***.72   slave3
39.***.***.21  slave4

发现master的ip是公网ip，将它换成内网Ip之后

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
# 39.**.***.128  master # 公网ip
172.**.***.86 master # 内网ip
123.**.***.54  slave1
123.**.***.90  slave2
59.**.***.72   slave3
39.***.***.21  slave4

再次启动namenode，问题解决

解决方案

[root@master ~]# systemctl enable rpcbind
[root@master ~]# systemctl start rpcbind
