ambari 第4步注册失败

Question

1台服务器  ambari离线单节点搭建HDP 之前在5台pc机上搭过都没有出现这种问题

hosts配置

127.0.0.1   localhost
192.168.20.210  hdp

openssl版本 openssl-1.0.1e-48.el6_8.3.x86_64

python版本 Python 2.6.6

系统是英文版的

发现一个奇怪的地方：

有问题的服务器

[root@hdp ambari-agent]# lsof -i:8440
COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
java    98425 root  798u  IPv6 2058074      0t0  TCP *:8440 (LISTEN)
java    98425 root  829u  IPv6 2058085      0t0  TCP hdp:8440->hdp:39067 (CLOSE_WAIT)
java    98425 root  863u  IPv6 2059278      0t0  TCP hdp:8440->hdp:39099 (CLOSE_WAIT)
java    98425 root  870u  IPv6 2063371      0t0  TCP hdp:8440->hdp:39312 (ESTABLISHED)
python2 99968 root    7r  IPv4 2076095      0t0  TCP hdp:39312->hdp:8440 (ESTABLISHED)

正常的集群：

[root@centos216 yum.repos.d]# lsof -i:8440
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    2150 root  741u  IPv6  13514      0t0  TCP *:8440 (LISTEN)

感觉和这个有关系但是不知道怎么解决

你的Hosts文件配置好了吗？
