大数据概述 可以用“5V + 1C”来概括：
Variety多样化Volume海量Velocity快速Vitality灵活Value价值性Complexity复杂 1.Hadoop生态
宏观: Hadoop为主的生态圈 hadoop flume........
狭义: apache hadoophadoop.apache.org
2.Hadoop(存储+计算+资源和作业调度)
hadoop1.x
HDFS 存储
MapReduce 计算+资源和作业调度
hadoop2.x企业正在用
HDFS 存储
MapReduce 计算
YARN 资源和作业调度平台 计算组件都会on yarn
hadoop3.x???
[*] EC技术：Erasure Encoding 简称EC，是Hadoop3给HDFS拓展的一种新特性，用来解决存储空间文件。
[*] YARN：提供YARN的时间轴服务V.2，以便用户和开发人员可以对其进行测试，并提供反馈意见。
[*] 优化Hadoop Shell脚本
[*] 重构Hadoop Client Jar包
[*] 支持随机Container
[*] MapReduce任务级本地优化
[*] 支持多个NameNode
[*] 部分默认服务端口被改变
[*] 支持文件系统连接器
[*] DataNode内部添加了负载均衡
[*] 重构后台程序和任务对管理
2.Maven部署

2.1解压

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /opt/software/apache-maven-3.3.9
Java version: 1.8.0_45, vendor: Oracle Corporation
Java home: /usr/java/jdk1.8.0_45/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-358.el6.x86_64", arch: "amd64", family: "unix"
Maven部署为二进制部署，解压配置环境变量
2.2配置mavne目录
2.3查看配置文件和 解压我们准备好的仓库文件
3.Hadoop编译
编译hadoop 通过Requirements我看可以知道需要安装jdk maven findbugs protocolBuffer cmake Zlib openssl-devel 等软件
3.1解压
3.2查看pom.xml
3.3查看BUILDING.txt
Requirements:编译软件环境要求
* Unix System
* JDK 1.7+
* Maven 3.0 or later
* Findbugs 1.3.9 (if running findbugs)
* ProtocolBuffer 2.5.0
* CMake 2.6 or newer (if compiling native code), must be 3.0 or newer on Mac
* Zlib devel (if compiling native code)
* openssl devel (if compiling native hadoop-pipes and to get the best HDFS encryption performance)
* Linux FUSE (Filesystem in Userspace) version 2.6 or above (if compiling fuse_dfs)
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
3.4 JDK部署
# tar -zxvf jdk-8u45-linux-x64.gz -C /usr/java# ls -ld /usr/java/* drwxr-xr-x 8 root root 4096 12月 15 2016 /usr/java/djdk1.7.0_79

drwxr-xr-x 8 uucp143 4096 10月7 2015 /usr/java/jdk1.8.0_65
# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_45
export JRE_HOME=/usr/java/jdk1.8.0_45/jre
# source /etc/profile
# java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
二进制版本解压，配置环境变量即可
3.5 MAVEN
上面我们已经安装maven和jdk检测版本是否满足我们编译软件要求
# mvn --version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)

export PATH=$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH # source /etc/profile
# findbugs -version
1.3.9
二进制安装解压，配置环境变量即可
3.7 PROTOCBUF编译安装
# tar xvfprotobuf-2.5.0.tar.gz # yum install -y gcc gcc-c++ make cmake ---编译环境
#cd /opt/software/protobuf-2.5.0
# ./configure --prefix=/usr/local/protobuf
# make && make install
# vim /etc/profile
export PROTOC_HOME=/usr/local/protobuf
export PATH=$PROTOC_HOME/bin:$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH
# source /etc/profile
# protoc --version
libprotoc 2.5.0
#
编译安装完成，配置环境变量
3.8 OTHER 依赖包
yum install -y openssl openssl-devel svn ncurses-devel zlib-devel libtool
yum install -y snappy snappy-devel bzip2 bzip2-devel \n
zo lzo-devel lzop autoconf automake
其他依赖包在系统安装ios都包含，执行yum安装即可
---------------------------------------------------------------------------------------------------------------------------------------
至此，编译hadoop需要的编译环境全部准备好，下面开启编译之路
---------------------------------------------------------------------------------------------------------------------------------------
3.9 编译
# tar xvf hadoop-2.8.1-src.tar.gz
# cd hadoop-2.8.1-src
# pwd
/opt/software/hadoop-2.8.1-src
#
mvn clean package -Pdist,native -DskipTests –Dtar
/opt/software/hadoop-2.8.1-src/hadoop-dist/target/hadoop-2.8.1.tar.gz
----编译好软件包保存位置 直接编译需要联网找依赖包，一般网络情况较好，需要几个小时
提前准备好依赖包编译方式
# tar xvf hadoop-2.8.1-src.tar.gz
# cd hadoop-2.8.1-src
# pwd
/opt/software/hadoop-2.8.1-src
# pwd
/opt/software/hadoop-2.8.1-src
# ls pom.xml---根据这个文件下载jar
pom.xml
[root@hado
-rw-r--r-- 1 root root96721446 4月25 09:57 .m2.tar.gz ---提前下好的仓库软件包
#tar xvf .m2.tar.gz –C /root ---不想download，使用提前准备好的仓库软件--->解压----->root家目录
# mvn clean package -Pdist,native -DskipTests –Dtar
