hue安装与部署

运行环境

  • centOS 6.6
  • hadoop 2.4.0
  • hive 1.2.0
  • spark 1.4.1
  • HUE 3.9

介绍:

Hue是一个开源的Apache Hadoop UI系统，最早是由Cloudera Desktop演化而来，由Cloudera贡献给开源社区，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等等。

HUE功能:

  • 数据库查询编辑器,支持 Hive, Impala, MySql, PostGres, Sqlite and Oracle
  • 动态查询仪表盘,支持 Solr
  • 支持 Spark 编辑器和仪表盘
  • 浏览器查看状态,支持 YARN, HDFS, Hive table Metastore, HBase, ZooKeeper
  • 支持 Pig Editor, Sqoop2, Oozie workflows 编辑器和仪表盘
  • 将数据导入hdfs

  • asciidoc
  • cyrus-sasl-devel
  • cyrus-sasl-gssapi
  • gcc
  • gcc-c++
  • krb5-devel
  • libtidy (for unit tests only)
  • libxml2-devel
  • libxslt-devel

添加maven源

sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo

安装依赖

sudo yum install 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

源码下载

下载，编译源码(hue 3.9),编译时间较长

git clone https://github.com/cloudera/hue.git branch-3.9
cd branch-3.9
make apps

编译完后也可以选择安装

make install

在desktop/conf/pseudo-distributed.ini中修改配置
假设所有服务都运行在testHost下

一些问题

使用hive 0.13.0时会报

can't fetch result之类的错误

是版本原因，升级hive版本为1.2.0问题消失

连接hive error

Could not install table: Error creating table sample_07: Could not start SASL: Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy mechs found (code THRIFTTRANSPORT): TTransportException('Could not start SASL: Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy mechs found',).

解决方案：

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