Hue集成Hadoop和Hive

一、环境准备

1、下载Hue： https://dl.dropboxusercontent.com/u/730827/hue/releases/3.12.0/hue-3.12.0.tgz

2、安装依赖

yum groupinstall -y "Development Tools" "Development Libraries"

yum install -y apache-maven ant asciidoc cyrus-sasl-devel cyrus-sasl-gssapi gcc gcc-c++ krb5-devel libxml2-devel libxslt-devel make mysql mysql-devel openldap-devel python-devel sqlite-devel gmp-devel libffi-devel

二、MySQL配置

1、 为root用户设置密码；

2、 配置远程登录

3、 创建hue数据库

4、 flush hosts

5、 flush privileges

三、解压、编译并安装

tar -zxvf hue-3.12.0.tgz -C /optcd /opt/ hue-3.12.0make apps

四、集成环境配置

1、配置HDFS

dfs.webhdfs.enabled

true

dfs.permissions.enabled

false

2、配置core-site.xml

vim /opt/hadoop-2.7.3/etc/hadoop/core-site.xml

*

hadoop.proxyuser.hue.groups

*

hadoop.proxyuser.root.hosts

*

hadoop.proxyuser.root.groups

httpfs.proxyuser.hue.hosts

*

httpfs.proxyuser.hue.groups

*

5、配置文件同步

将以上配置文件同步到其他Hadoop主机

添加hue用户及用户组

sudo useradd huesudo chmod -R 755 /opt/hue-3.12.0/

sudo chown -R hue:hue /opt/hue-3.12.0/

五、Hue的配置

vim  /opt/hue-3.8.1/desktop/conf/hue.ini

1、配置HDFS超级用户

# This should be the hadoop cluster admin default_hdfs_superuser=xfvm

超级用户参见HDFS WEBUI

 

2、配置desktop

[desktop]

# Set this to a random string, the longer the better.

# This is used for secure hashing in the session store.

secret_key=jFE93j;2[290-eiw.KEiwN2s3['d;/.q[eIW^y#e=+Iei*@Mn

# Webserver listens on this address and port

http_host=xfvm04

http_port=8888

# Time zone name

time_zone=Asia/Shanghai

3、配置HDFS

[[hdfs_clusters]]

# HA support by using HttpFs

[[[default]]]

# Enter the filesystem uri

fs_defaultfs=hdfs://xfvm01:8020

# 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://xfvm01:50070/webhdfs/v1

4、配置YARN

[[[default]]]

# Enter the host on which you are running the ResourceManager

resourcemanager_host=xfvm01

# The port where the ResourceManager IPC listens on

resourcemanager_port=8132

#参考yarn-site.xml中的yarn.resourcemanager.address.rm1

# 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://xfvm01:8188

#参考yarn-site.xml中的yarn.resourcemanager.webapp.address.rm1

# URL of the ProxyServer API

proxy_api_url=http://xfvm01:8130

#参考yarn-site.xml中的yarn.resourcemanager.scheduler.address.rm1

#端口固定：8088

# URL of the HistoryServer API

#参考mapred-site.xml中的mapreduce.jobhistory.webapp.address

history_server_api_url=http://xfvm03:19888

5、配置HIVE

[beeswax]

# Host where HiveServer2 is running.

# If Kerberos security is enabled, use fully-qualified domain name (FQDN).

hive_server_host=xfvm04

# Port where HiveServer2 Thrift server runs on.

hive_server_port=10000

6、配置zookeeper

[zookeeper]

[[clusters]]

[[[default]]]

# Zookeeper ensemble. Comma separated list of Host/Port.

# e.g. localhost:2181,localhost:2182,localhost:2183

host_ports=xfvm02:2181,xfvm03:2181,xfvm04:2181

7、配置MySQL

# 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=xfvm04

# 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=123456

8、配置禁用组件（还未安装的组件）

# Comma separated list of apps to not load at server startup.

# e.g.: pig,zookeeper app_blacklist=pig,hbase,spark,impala,oozie

 

六、Hive环境变量的配置（hiveserver2，使用Mysql作为独立的元数据库）

1、编辑hive-site.xml

hive.metastore.uris

thrift://192.168.10.24:9083

Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.

hive.server2.thrift.bind.host

192.168.10.24

Bind host on which to run the HiveServer2 Thrift service.

七、MySQL初始化

进入hue安装目录的/bin目录

./hue syncdb./hue migrate

八、启动顺序

1、启动Hive metastore

$ bin/hive --service metastore &

2、启动hiveserver2

$ bin/hive --service hiveserver2 &

3、启动Hue

$bin/supervisor

./hue runserver 0.0.0.0:8088

4、浏览器：http://xfvm04:8888，输入用户名和密码即可登录

问题：

thrift.transport.TTransport.TTransportException: Could not start SASL: Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy mechs found

yum install cyrus-sasl-plain  cyrus-sasl-devel  cyrus-sasl-gssapi
