UDH 常见问题及解决方案
Q1 ：确认主机时，主机无法安装
A ：各个服务器需要建立针对自身的免密码登陆服务
# cd ~/.ssh
# cat id_rsa.pub >>authorized_keys
Q2 ：无法连接到 master 的 8440 端口
A ： Openssl 版本过低导致连接失败，将 Openssl 升级
Q3 ： Install DataNode 超时，报错： Python script has been killed due to timeout
A ：超时问题一般重新操作即可， ReTry 。
Q4 ： NameNode 启动报错： UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position 221: ordinal not in range(128)
A: 这是由于编码不一致导致的，修改 ambari-server 的格式，修改为 en_US.UTF_8.
# vim /etc/sysconfig/i18n
修改编码格式为 en_US.UTF_8
# source /etc/sysconfig/i18n
Q5 ： # /usr/bin/yum -d 0 -e 0 -y install udh-zookeeper-rest

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
yum.repos.d
