配置Hue的主要步骤：

• 安装所需的rpm包
• 编辑Hadoop的配置文件
• 安装Hue
• 启动Hue及验证

安装所需的rpm包

yum install ant
yum install asciidoc
yum install cyrus-sasl-devel
yum install cyrus-sasl-gssapi
yum install gcc
yum install gcc-c++
yum install krb5-devel

# for unit tests only
yum install libtidy 

yum install libxml2-devel
yum install libxslt-devel
yum install make
# yum install mvn (from maven package or maven3 tarball)
yum install mysql
yum install mysql-devel
yum install openldap-devel
yum install python-devel
yum install sqlite-devel

# for version 7+
yum install openssl-devel

yum install gmp-devel

编辑Hadoop的配置文件

参数文件	参数	参考值	说明
hdfs-site.xml	dfs.webhdfs.enabled	true	开启webhdfs功能
core-site.xml	hadoop.proxyuser.root.hosts	*	设置Hadoop集群的代理用户，*表示任何用户
core-site.xml	hadoop.proxyuser.root.groups	*	设置Hadoop集群的代理用户组

hdfs-site.xml

<property>
    <name>dfs.webhdfs.enabledname>
    <value>truevalue>
property>

core-site.xml

<property>
    <name>hadoop.proxyuser.root.hostsname>
    <value>*value>
property>
<property>
    <name>hadoop.proxyuser.root.groupsname>
    <value>*value>
property>

安装Hue

解压hue-3.7.0-cdh5.4.2.tar.gz

mkdir -p /root/tools
tar -zxvf hue-3.7.0-cdh5.4.2.tar.gz -C ~/training/

编译安装：注意系统时间

cd ~/training/hue-3.7.0-cdh5.4.2
PREFIX=/root/training/ make install

bug解决

# 缺少64位的
yum install -y glibc-devel

/bin/bash: rsync: command not found

yum install -y rsync

添加用户hue

adduser hue
chown -R hue.hue /root/training/hue/

修改hue.ini($HUE_HOME/desktop/conf/hue.ini)参数文件

参数	参考值
http_host	hadoop25pseudo
http_port	8888
server_user	root
server_group	root
default_user	root
default_hdfs_superuser	root
fs_defaultfs	hdfs://hadoop25pseudo:9000
webhdfs_url	http://hadoop25pseudo:50070/webhdfs/v1

resourcemanager_api_url	http://hadoop25pseudo:8088
proxy_api_url	http://hadoop25pseudo:8088
history_server_api_url	http://hadoop25pseudo:19888

find . -name hue.ini
# ./desktop/conf/hue.ini
cd desktop/conf/
vi hue.ini

http_host=hadoop25pseudo

启动Hue及验证

启动Hadoop相关组件start-all.sh

启动Hue：

cd ~/training/hue/build/env
bin/supervisor
