Ambari安装HDP问题：User root is not allowed to impersonate anonymous.User: hcat is not allowed to impersonate ambari-qa

User root is not allowed to impersonate anonymous

• 修改hadoop 配置文件 etc/hadoop/core-site.xml,加入如下配置项

<property>     <name>hadoop.proxyuser.root.hosts</name>     <value>*</value> </property> <property>     <name>hadoop.proxyuser.root.groups</name>     <value>*</value> </property>

    hadoop.proxyuser.root.hosts配置项名称中root部分为报错User:* 中的用户名部分

    例如User: zhaoshb is not allowed to impersonate anonymous则需要将xml变更为如下格式

<property>     <name>hadoop.proxyuser.zhaoshb.hosts</name>     <value>*</value> </property> <property>     <name>hadoop.proxyuser.zhaoshb.groups</name>     <value>*</value> </property>
