hue学习文档地址：
我目前使用的是hue-3.7.0-cdh5.3.6
hue（HUE=Hadoop User Experience）
Hue是一个开源的Apache Hadoop UI系统，由Cloudera Desktop演化而来，最后Cloudera公司将其贡献给Apache基金会的Hadoop社区，它是基于Python Web框架Django实现的。
通过使用Hue我们可以在浏览器端的Web控制台上与Hadoop集群进行交互来分析处理数据，例如操作HDFS上的数据，运行MapReduce Job，执行Hive的SQL语句，浏览HBase数据库等等。
hue特点：
能够支持各个版本的hadoop
hue默认数据库：sql lite
文件浏览器：对数据进行增删改查
hue下载src包进行一次编译，二次编译，在这用的是已经一次编译
hue部署：
1、下载依赖包：yum源安装
sudo yum -y install ant asciidoc cyrus-sasl-devel cyrus-sasl-gssapi gcc gcc-c++ krb5-devel libtidy libxml2-devel libxslt-devel mvn mysql mysql-devel openldap-devel python-devel sqlite-devel openssl-devel
sudo yum install ant asciidoc cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-plain gcc gcc-c++ krb5-devel libffi-devel libxml2-devel libxslt-devel make mysql mysql-devel openldap-devel python-devel sqlite-devel gmp-devel
2、解压hue tar包
tar -zxvf hue-3.7.0-cdh5.3.6.tar.gz -C /指定的目录
3、二次编译
进入hue目录：执行make apps 会出现个build目录
错误：（centos 7会有）
error: static declaration of ‘X509_REVOKED_dup’ follows non-static declaration
static X509_REVOKED * X509_REVOKED_dup(X509_REVOKED *orig) {
^

X509_REVOKED *X509_REVOKED_dup(X509_REVOKED *rev);
^
error: command 'gcc' failed with exit status 1
给下面两个删掉：/usr/include/openssl/x509.h -》751、752行
X509_REVOKED *X509_REVOKED_dup(X509_REVOKED *rev);
X509_REQ *X509_REQ_dup(X509_REQ *req);
##必须删掉，注释不行
4、进入到hue-3.7.0-cdh5.3.6/desktop/conf
配置hue.ini文件:
secret_key=jFE93j;2[290-eiw.KEiwN2s3['d;/.q[eIW^y#e=+Iei*@Mn<qW5o
http_host=hadoop01.xningge.com
http_port=8888
time_zone=Asia/Shanghai
5、启动hue
两种方式
1-->cd build/env/bin---》./supervisor
2-->build/env/bin/supervisor
6、浏览器访问hue
主机名+8888
创建用户名和密码
1、hdfs的配置
在hdfs-site.xml中配置
<property>
<name>dfs.webhdfs.enabled</name>
<value>true</value>
</property>
在core-site.xml中配置
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
2、重新启动hdfs进程
sbin/start-yarn.sh
3、hue配置
[[hdfs_clusters]]
# HA support by using HttpFs
[[[default]]]
# Enter the filesystem uri
fs_defaultfs=hdfs://hadoop01.xningge.com:8020
# NameNode logical name.
## logical_name=
# Use WebHdfs/HttpFs as the communication mechanism.
# Domain should be the NameNode or HttpFs host.
# Default port is 14000 for HttpFs.
webhdfs_url=http://hadoop01.xningge.com:50070/webhdfs/v1
# This is the home of your Hadoop HDFS installation
hadoop_hdfs_home=http://www.likecs.com/opt/modules/cdh/hadoop-2.5.0-cdh5.3.6
# Use this as the HDFS Hadoop launcher script

# Change this if your HDFS cluster is Kerberos-secured

## umask=022
# Directory of the Hadoop configuration
hadoop_conf_dir=http://www.likecs.com/opt/modules/cdh/hadoop-2.5.0-cdh5.3.6/etc/hadoop
[[yarn_clusters]]
[[[default]]]
# Enter the host on which you are running the ResourceManager
resourcemanager_host=hadoop01.xningge.com
# The port where the ResourceManager IPC listens on
resourcemanager_port=8032
# Whether to submit jobs to this cluster
submit_to=True
# Resource Manager logical name (required for HA)
## logical_name=
# Change this if your YARN cluster is Kerberos-secured
## security_enabled=false
# URL of the ResourceManager API
resourcemanager_api_url=http://hadoop01.xningge.com:8088
# URL of the ProxyServer API
proxy_api_url=http://hadoop01.xningge.com:8088
# URL of the HistoryServer API
history_server_api_url=http://hadoop01.xningge.com:19888
eg:此配置都是伪分布式模式
4、启动hue服务
build/env/bin/supervisor
hue与hive配置1、hive配置
在hive-site.xml配置
