hadoop部署、启动全套过程
Hadoop是Apache基金会的开源项目，为开发者提供了一个分布式系统的基础架构，用户可以在不了解分布式系统的底层细节的情况下开发分布式的应用，充分利用集群的强大功能，实现高速运算和存储。Hadoop项目中包括一个分布式的文件系统ＨＤＦＳ，一个分布式的并行编程框架mapreduce，以及包括hive,hbase,mahout,pig,zookeeper,avro,chukwa在内的诸多子项目。
Hadoop主要的两部分分别是分布式存储ＨＤＦＳ和分布式计算mapreduce。Hdfs是一个master/slave的结构，就一般的部署来说，在master上只运行一个namenode，而在每一个slave上运行一个datanode。Mapreduce是一个编程模型，用以进行大数据量的计算。Mapreduce的名字源于这个模型中的两项核心操作：map和reduce。Map是把一组数据一对一地映射为另外一组数据，reduce是对一组数据进行归约，映射和归约的规则都是由一个函数指定。
整个hadoop族群中包括很多项目，如：
ＨＤＦＳ：分布式文件系统，是ＧＦＳ的开源实现。
Mapreduce:分布式并行编程模型和程序执行框架，是google公司的mapreduce的开源实现。
Common:是整个hadoop项目的核心，包括一组分布式文件系统和通用ＩＯ的组件和接口(序列化，javaprc和持久化数据结构)。
Avro:一种支持搞笑，跨语言的rpc以及永久存储数据的序列化实现。
Pig: 一种数据流语言和运行环境，用以检索非常大的数据集，运行在mapreduce和hdfs的集群上。
Hive: 一个分布式，按列存储的数据仓库。Hive管理hdfs中存储的数据，并提供基于sql的查询语言(由运行时引擎翻译成mapreduce作业)用以查询数据。
Hbase: 一个分布式，按列存储的额数据库。Hbase使用hdfs作为底层存储，同时支持mapreduce的批量式计算和点查询(随机读取)。
Mahout:一个在hadoop上运行的机器学习类库。
Zookeeper:一个分布式，可用性高的协调服务。Zookeeper提供分布式锁之类的基本服务用于构建分布式应用。
Cassandra：是一套开源分布式nosql数据库系统，用于存储收件箱等简单格式数据，集google bigtable的数据模型与amazon dynamo的完全分布式架构于一身。
从最终用户的角度来看，它就像传统的文件系统一样，可以通过目录路径对文件执行crud操作。一个ＨＤＦＳ集群是由一个namenode和若干个datanode组成的。Namenode主节点是主服务器，管理文件系统的命名空间和客户端对文件的访问操作；datanode是集群中的一般节点，负责节点数据的存储。客户端通过namenode向datanode节点交互访问文件系统，联系namenode获得文件的元数，而文件io操作则是直接和datanode进行交互的额。Hdfs允许用户以文件的形式存储数据，文件被分成若干个数据块，典型数据块大小是６４ＭＢ。Hdfs的文件通常是按照６４mb被切分为不同的数据块(block)的。每个数据块尽可能分散在不同的datanode中，而若干个数据块存放在一组datanode上。Namenode执行文件系统的命名空间操作，它也负责数据块到具体datanode的映射。Datanode负责处理文件系统客户端的文件读/写操作，并在namenode的统一调度下进行数据块的创建，删除和复制工作。
Mapreduce编写的程序和hadoop程序的编译都依赖于jdk。

修改conf/hadoop-env.sh文件，定义ＪＡＶＡ_ＨＯＭＥ的路径然后到bin目录下运行./hadoop命令，会输出如何使用hadoop。

本地操作：
默认情况下就是这个模式，
Mkdir input
cp conf/*.xml input
运行hadoop自带的hadoop-examples*.jar来搜索input文件夹中的含有dfs[a-z]的字符串并统计出现数量，
bin/hadoop jarhadoop-examples-*.jar grep input output1 'dfs[a-z.]'
输出：

以分布式模式运行，
修改以下文件，
conf/core-site.xml:
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
conf/hdfs-site.xml:

检查你是否可以ssh到本地，
$ ssh localhost
如果你不可以，用执行以下命令
$ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
接下来对一个新的分布式文件系统进行format,
$ bin/hadoopnamenode -format
