4,结构示意图：

二，Hue的安装和部署

1，下载源码包CDH5.3.6版本：

http://archive.cloudera.com/cdh5/cdh/5/hue-3.7.0-cdh5.3.6.tar.gz

2,虚拟机连接互联网
3，安装hue所以依赖的系统包，针对不同的unix系统,需要root权限

yum install ant asciidoc cyrus-sasl-devel cyrus-sasl-gssapi gcc gcc-c++ krb5-devel libtidy libxml2-devel libxslt-devel openldap-devel python-devel sqlite-devel openssl-devel mysql-devel gmp-devel

4，解压hue源码包到指定的目录下

[root@xingyunfei001 app]# tar zxf hue-3.7.0-cdh5.3.6.tar.gz 

5,编译源码包

[root@xingyunfei001 app]# cd hue-3.7.0-cdh5.3.6/

[root@xingyunfei001 hue-3.7.0-cdh5.3.6]# make apps

6，修改配置文件hue.ini

vi /opt/app/hue-3.7.0-cdh5.3.6/desktop/conf/hue.ini

  # Set this to a random string, the longer the better. # This is used for secure hashing in the session store. secret_key=qpbdxoewsqlkhztybvfidtvwekftusgdlofbcfghaswuicmqp # Webserver listens on this address and port http_host=xingyunfei001.comcn http_port=8888 # Time zone name time_zone=Asia/Shanghai

7,启动hue

[hadoop001@xingyunfei001 hue-3.7.0-cdh5.3.6]$ build/env/bin/supervisor

8,浏览器查看

http://xingyunfei001.com.cn:8888/accounts/login/?next=/

三，hue集成hadoop2.x

1,修改hadoop的hdfs-site.xml配置文件：

<property>
  <name>dfs.webhdfs.enabled</name>
  <value>true</value>
</property>

2,修改hadoop的core-site.xml配置文件

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

3,修改hue的hue.ini配置文件

[hadoop]

  # Configuration for HDFS NameNode
  # ------------------------------------------------------------------------
  [[hdfs_clusters]]
    # HA support by using HttpFs

    [[[default]]]
      # Enter the filesystem uri
      fs_defaultfs=hdfs://xingyunfei001.com.cn: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://xingyunfei001.com.cn:50070/webhdfs/v1

      # 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_hdfs_home=/opt/app/hadoop_2.5.0_cdh

      hadoop_bin=/opt/app/hadoop_2.5.0_cdh/bin

      hadoop_conf_dir=/opt/app/hadoop_2.5.0_cdh/etc/hadoop

  [[yarn_clusters]]

    [[[default]]]
      # Enter the host on which you are running the ResourceManager
      resourcemanager_host=xingyunfei001.com.cn

      # 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://xingyunfei001.com.cn:8088

      # URL of the ProxyServer API
      proxy_api_url=http://xingyunfei001.com.cn:8088

      # URL of the HistoryServer API
      history_server_api_url=http://xingyunfei001.com.cn:19888

      # In secure mode (HTTPS), if SSL certificates from Resource Manager's
      # Rest Server have to be verified against certificate authority
      ## ssl_cert_ca_verify=False

    # HA support by specifying multiple clusters
    # e.g.

    # [[[ha]]]
      # Resource Manager logical name (required for HA)
      ## logical_name=my-rm-name

4,重新启动hdfs

[hadoop001@xingyunfei001 hadoop_2.5.0_cdh]$ sbin/start-all.sh

[hadoop001@xingyunfei001 hadoop_2.5.0_cdh]$ sbin/mr-jobhistory-daemon.sh start historyserver

5,重新启动hue服务器

[hadoop001@xingyunfei001 hue-3.7.0-cdh5.3.6]$ build/env/bin/supervisor

6,查看测试结果

四，hue集成hive

1,配置hue.ini配置文件

[beeswax]

  # Host where HiveServer2 is running.
  # If Kerberos security is enabled, use fully-qualified domain name (FQDN).
  hive_server_host=xingyunfei001.com.cn

  # Port where HiveServer2 Thrift server runs on.
  hive_server_port=10000

  # Hive configuration directory, where hive-site.xml is located
  hive_conf_dir=/opt/app/hive_0.13.1_cdh/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

2,修改hive的hive-site.xml文件配置metastore server

<property>
    <name>hive.metastore.uris</name>
    <value>thrift://xingyunfei001.com.cn:9083</value>
</property>

3,启动metastore server(先启动)和hiveserver2

nohup bin/hive --service metastore &

[hadoop001@xingyunfei001 hive_0.13.1_cdh]$ bin/hiveserver2

4,修改hdfs文件系统的/tmp权限

[hadoop001@xingyunfei001 hadoop_2.5.0_cdh]$ bin/hdfs dfs -chmod -R o+x /tmp

5,查看配置是否生效

select id,url,referer from track_log limit 10;

五，hive集成RDBMS

1,修改hue.ini配置文件

  [[databases]]
    # sqlite configuration.
    [[[sqlite]]]
      # Name to show in the UI. nice_name=SQLite # For SQLite, name defines the path to the database. name=/opt/app/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. [[[mysql]]] # 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=mysqldb # 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=xingyunfei001.com.cn # Port the database server is listening to. Defaults are: # 1. MySQL: 3306 # 2. PostgreSQL: 5432 # 3. Oracle Express Edition: 1521 port=3306 # Username to authenticate with when connecting to the database. user=root # Password matching the username to authenticate with when # connecting to the database. password=root # Database options to send to the server when connecting. # https://docs.djangoproject.com/en/1.4/ref/databases/ ## options={}

2,重新启动hue

build/env/bin/supervisor
