Hadoop官方网站中只提供了32位的Hadoop-2.2.0.tar.gz，如果要在64位Ubuntu下部署Hadoop-2.2.0，就需要重新编译源码包，生成64位的部署包。
建议以下操作使用root账户，避免出现权限不足的问题。
Linux系统：64位Ubuntu 14.04.1
安装JDK 安装Maven请参考文章《Ubuntu 14.04.1中安装Maven》。
下载Hadoop源码wget http://mirror.bit.edu.cn/apache/hadoop/common/hadoop-2.2.0/hadoop-2.2.0-src.tar.gz
解压tar -xzf hadoop-2.2.0-src.tar.gz
编译源代码cd hadoop-2.2.0-src mvn package -Pdist,native -DskipTests -Dtar
第1次编译：失败（hadoop pom.xml的bug）错误信息：
[ERROR] Failed to execute goal on project hadoop-auth: Could not resolve dependencies for project org.apache.hadoop:hadoop-auth:jar:2.2.0: Could not transfer artifact org.mortbay.jetty:jetty:jar:6.1.26 from/to central (https://repo.maven.apache.org/maven2): GET request of: org/mortbay/jetty/jetty/6.1.26/jetty-6.1.26.jar from central failed: SSL peer shut down incorrectly -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

解决办法：
这是hadoop的一个bug，在pom.xml中添加下面patch即可，详见https://issues.apache.org/jira/browse/HADOOP-10110 。
编辑`hadoop-common-project/hadoop-auth/pom.xml`文件：
vi hadoop-common-project/hadoop-auth/pom.xml
在<dependencys></dependencys>节点中插入：
<dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-util</artifactId> <scope>test</scope> </dependency>
第2次编译：失败（未安装protoc）错误信息：
[ERROR] Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:2.2.0:protoc (compile-protoc) on project hadoop-common: org.apache.maven.plugin.MojoExecutionException: 'protoc --version' did not return a version -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

解决办法：
根据错误信息可以知道是因为没有安装protoc。
wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz tar -xzf protobuf-2.5.0.tar.gz cd protobuf-2.5.0 ./configure make make check make install
其中，在执行./configure命令是会报如下错误：
checking whether to enable maintainer-specific portions of Makefiles... yes checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... no checking for gcc... no checking for cc... no checking for cl.exe... no configure: error: in `/home/hadoop/protobuf-2.5.0': configure: error: no acceptable C compiler found in $PATH See `config.log' for more details
提示我们找不到C编译器，因此我们还需要安装C编译器。
ubuntu提供了集成gcc等编译器的基本编译工具`build-essential`，安装起来也比较方便，只需要一行命令：
apt-get install build-essential
安装过程中可能会提示包找不到，建议先更新下软件源：
apt-get update
安装之后验证protobuf的时候可能会报错以下错误：
