在ubuntu16.06 64位上編譯hadoop2.7.5

首先要下載hadoop源碼包，並放在linux目錄中進行解壓。解壓後能夠看到文件目錄的結構：

在BUILDING.txt文件中有對編譯的要求。

Requirements:

* 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)

1. 安裝依賴

* Maven
  $ sudo apt-get -y install maven
* Native libraries
  $ sudo apt-get -y install build-essential autoconf automake libtool cmake zlib1g-dev pkg-config libssl-dev
* ProtocolBuffer 2.5.0 (required)
  $ sudo apt-get -y install libprotobuf-dev protobuf-compiler

2. 編譯hadoop

進入hadoop source src目錄

mvn package -Pdist,native -DskipTests -Dtar

編譯好的二進制包在以下目錄：

hadoop-2.7.5-src/hadoop-dist/target/
