编译hadoop

uos@uos-PC:~/wss/hadoop-rel-release-2.8.5$ cat BUILDING.txt

Requirements:
 
* Windows 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
* Windows SDK 7.1 or Visual Studio 2010 Professional
* Windows SDK 8.1 (if building CPU rate control for the container executor)
* zlib headers (if building native code bindings for zlib)
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
* Unix command-line tools from GnuWin32: sh, mkdir, rm, cp, tar, gzip. These
  tools must be present on your PATH.
* Python ( for generation of docs using 'mvn site')

sudo apt install findbugs

只有configure.ac，没有configure 运行autoconf命令来生成configure，但是报以下错误：

uos@uos-PC:~/wss/protobuf/protobuf-2.5.0$ autoconf
configure.ac:17: error: possibly undefined macro: AM_MAINTAINER_MODE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:32: error: possibly undefined macro: AM_INIT_AUTOMAKE
configure.ac:49: error: possibly undefined macro: AM_CONDITIONAL
configure.ac:75: error: possibly undefined macro: AC_PROG_LIBTOOL
configure.ac:140: error: possibly undefined macro: AC_CXX_STL_HASH

运行这个命令解决以上的错误：autoreconf --install
