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) {
^

^
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
hue和hadoop的组件配置
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=/opt/modules/cdh/hadoop-2.5.0-cdh5.3.6
# Use this as the HDFS Hadoop launcher script
hadoop_bin=/opt/modules/cdh/hadoop-2.5.0-cdh5.3.6/bin
# Change this if your HDFS cluster is Kerberos-secured
## security_enabled=false
# Default umask for file and directory creation, specified in an octal value.
## umask=022
# Directory of the Hadoop configuration
hadoop_conf_dir=/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
<property>
<name>hive.server2.thrift.bind.host</name>
<value>hadoop01.xningge.com</value>
</property>
<property>
<name>hive.metastore.uris</name>
<value>hadoop01.xningge.com:9083</value>
</property>
2、启动hive服务
bin/hiveserver2 &
bin/hive --service metastore &
3 、hue配置
修改hue.ini文件
[beeswax]
# Host where HiveServer2 is running.
# If Kerberos security is enabled, use fully-qualified domain name (FQDN).
hive_server_host=hadoop01.xningge.com
# Port where HiveServer2 Thrift server runs on.
hive_server_port=10000
# Hive configuration directory, where hive-site.xml is located
hive_conf_dir=/opt/modules/cdh/hive-0.13.1-cdh5.3.6/conf
# Timeout in seconds for thrift calls to Hive service
server_conn_timeout=120
# Choose whether Hue uses the GetLog() thrift call to retrieve Hive logs.
# If false, Hue will use the FetchResults() thrift call instead.
## use_get_log_api=true
# Set a LIMIT clause when browsing a partitioned table.
# A positive value will be set as the LIMIT. If 0 or negative, do not set any limit.
## browse_partitioned_table_limit=250
# A limit to the number of rows that can be downloaded from a query.
# A value of -1 means there will be no limit.
# A maximum of 65,000 is applied to XLS downloads.
## download_row_limit=1000000
# Hue will try to close the Hive query when the user leaves the editor page.
# This will free all the query resources in HiveServer2, but also make its results inaccessible.
## close_queries=false
# Thrift version to use when communicating with HiveServer2
## thrift_version=5
hue与关系型数据库配置
[librdbms]
# The RDBMS app can have any number of databases configured in the databases
# section. A database is known by its section name
# (IE sqlite, mysql, psql, and oracle in the list below).
[[databases]]
# sqlite configuration.
[[[sqlite]]] //注意这里一定要取消注释
# Name to show in the UI.
nice_name=SQLite
# For SQLite, name defines the path to the database.
name=/opt/modules/hue-3.7.0-cdh5.3.6/desktop/desktop.db
# Database backend to use.
engine=sqlite
# Database options to send to the server when connecting.
# https://docs.djangoproject.com/en/1.4/ref/databases/
## options={}
# mysql, oracle, or postgresql configuration.
##注意：这里的数据不能改动，默认是hue的数据库
[[[mysql]]] //注意这里一定要取消注释
# Name to show in the UI.
nice_name="My SQL DB"
# For MySQL and PostgreSQL, name is the name of the database.
# For Oracle, Name is instance of the Oracle server. For express edition
# this is ‘xe‘ by default.
name=sqoop//这个name是数据库表名
# Database backend to use. This can be:
# 1. mysql
# 2. postgresql
# 3. oracle
engine=mysql
# IP or hostname of the database to connect to.
host=hadoop01.xningge.com
# Port the database server is listening to. Defaults are:

# 2. PostgreSQL: 5432
# 3. Oracle Express Edition: 1521
port=3306
# Username to authenticate with when connecting to the database.
user=xningge
# Password matching the username to authenticate with when
# connecting to the database.
password=???
# Database options to send to the server when connecting.
# https://docs.djangoproject.com/en/1.4/ref/databases/
## options={}
hue与zookeeper配置
只需修改hue.ini文件
host_ports=hadoop01.xningge.com:2181
启动zookeeper：
hue与oozie的配置
修改：hue.ini文件
[liboozie]
oozie_url=http://hadoop01.xningge.com:11000/oozie
如果没有出来的：
修改：oozie-site.xml
<property>
<name>oozie.service.WorkflowAppService.system.libpath</name>
<value>/user/oozie/share/lib</value>
</property>
到oozie目录下重新创建sharelib库：
bin/oozie-setup.sh sharelib create -fs hdfs://hadoop01.xningge.com:8020 -locallib oozie-sharelib-4.0.0-cdh5.3.6-yarn.tar.gz
启动oozie：bin/oozied.sh start
hue与hbase的配置
修改hue.ini文件:
hbase_clusters=(Cluster|hadoop01.xningge.com:9090)
hbase_conf_dir=/opt/cdh_5.3.6/hbase-0.98.6-cdh5.3.6/conf
修改hbase-site.xml,添加以下配置：
<property>
<name>hbase.regionserver.thrift.http</name>
<value>true</value>
</property>
<property>
<name>hbase.thrift.support.proxyuser</name>
<value>true</value>
</property>
启动hbase：
bin/start-hbase.sh
bin/hbase-daemon.sh start thrift
##hbase完全分布式
hbase_clusters=(Cluster1|hostname:9090,Cluster2|hostname:9090,Cluster3|hostname:9090)
