HUE簡介
Hue是一個開源的Apache Hadoop UI系統，由Cloudera Desktop演化而來，最後Cloudera公司將其貢獻給Apache基金會的Hadoop社區，用Python Web框架Django實現的。通過使用Hue我們可以在瀏覽器端的Web控制檯上與Hadoop集羣進行交互來分析處理數據，例如操作HDFS上的數據，運行MapReduce Job，執行Hive的SQL語句，瀏覽HBase數據庫等等。
由於工作需要，最近研究了一下hue的安裝配置、使用、編碼調試，網上資料比較少，現將本人實際安裝步驟記錄一下分享出來，希望對需要的同學有所幫助
安裝環境
聲明：我全程在root用戶下安裝，其實不妥，應更換普通用戶如hue
centos-7.6
mysql-8.0.17
hadoop-2.8.5
JDK：jdk-8u171-linux-x64
Maven：apache-maven-3.6.1-bin
Pyhon-2.7.5
Hue: CHD 5.16.2(相當於4.X版本)
安裝依賴
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 -y
下載解壓並編譯
hue下載地址：
https://github.com/cloudera/hue/releases
下載zip版
解壓：
unzip .....
進入到hue目錄後，開始進行編譯，編譯需要python2.7的環境，centos7自帶2.7.5
也可以自行升級
下載python安裝包
wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz
解壓
tar -xzvf Python-2.7.14.tgz
安裝依賴
yum -y install gcc gcc-c++ libstdc++-devel
編譯安裝
cd Python-2.7.14
./configure
make all
make install
make clean
make distclean
檢測成功與否
python --version
編譯hue
進入hue目錄執行
make clean
make apps
然後開始等待（過程大概十分鐘左右）
編譯時遇到的錯誤：
缺少my_conf.h配置文件
https://blog.csdn.net/qq_38924171/article/details/101426144#commentBox
解決！
maven plugin插件錯誤
需要刪除兩個文件，文章最後有錯誤解決
配置文件：
位置在/hue/desktop/conf/pseudo-distributed.ini
我只配了mysql，hive，hdfs，resourcemanager

增加hue用戶：adduser hue
-----------------------------------------------
訪問8000端口，報錯OperationalError: attempt to write a readonly database
原因是 /opt/hue/desktop/desktop.db 只有讀權限
# chmod +777 desktop.db 即可
再訪問報錯 OperationalError: unable to open database file
原因是包含desktop.db的文件夾對hue用戶也是隻能讀不能寫的
[root@hadoop01 hue]# chown -R hue:root *
啓動成功
錯誤：
無法連接到hdfs文件系統
在hadoop配置文件core-site,xml中加入

<property>

有幾個用戶就加幾對，大家都要訪問hdfs界面，這裏的用戶是指hue的操作用戶
簡單的用一下
在mysql中查一張表
在hive中查一張表
看看hdfs上的數據
