ubuntu1404_64单机安装Hadoop2.7.3

JDK、Hadoop、Hive官网下载，Hive默认（嵌入式derby 模式）
http://hadoop.apache.org/releases.html
http://www.apache.org/dyn/closer.cgi/hive/
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
参考文档
http://www.powerxing.com/install-hadoop/
创建用户和组，设置密码

root@hive:~# useradd -m hadoop -s /bin/bash
root@hive:~# passwd hadoop
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully

切换hadoop用户后，配置SSH免密登录

root@hive:~# su hadoop
hadoop@hive:/root$ cd 
hadoop@hive:~$ ssh-keygen -t rsa -P '' 
#密钥默认存放在/home/hadoop/.ssh/目录下
hadoop@hive:~$ cat ./.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
hadoop@hive:~$ chmod 0600 !$
chmod 0600 ~/.ssh/authorized_keys

验证

配置Java环境

hadoop@hive:~# tar xvf jdk-8u111-linux-x64.tar.gz -C /usr/share/java/
hadoop@hive:~# vim .bash_profile
hadoop@hive:~# cat !$
cat .bash_profile
export JAVA_HOME=/usr/share/java/jdk1.8.0_111/
export PATH=$PATH:$JAVA_HOME/bin
hadoop@hive:~# source !$
source .bash_profile
hadoop@hive:~# java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

Hadoop配置
core-site.xml：包括HDFS、MapReduce的I/O以及namenode节点的url（协议、主机名、端口）等核心配置，datanode在namenode上注册后，通过此url跟client交互

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/core-site.xml 
<configuration>
        <property>
             <name>fs.defaultFS</name>
             <value>hdfs://localhost:9000</value>
        </property>
</configuration>

hdfs-site.xml： HDFS守护进程配置，包括namenode，secondary namenode，datanode

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/hdfs-site.xml 
<configuration>
        <property>
             <name>dfs.replication</name>
             <value>1</value>
        </property>
</configuration>

mapred-site.xml：MapReduce守护进程配置，包括jobtracker和tasktrackers

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/mapred-site.xml
<configuration>
        <property>
             <name>mapreduce.framework.name</name>
             <value>yarn</value>
        </property>
</configuration>

全局资源管理配置
http://www.cnblogs.com/gw811/p/4077318.html

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/yarn-site.xml 
<configuration>
   <property>
      <name>yarn.nodemanager.aux-services</name> 
      <value>mapreduce_suffle</value>
   </property> 
</configuration>

配置与hadoop运行环境相关的变量

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/hadoop-env.sh
export JAVA_HOME=/usr/share/java/jdk1.8.0_111/

nameNode 格式化并启动，如果修改了hostname，/etc/hosts文件也需要添加本地解析，否则初始化会报错namenode unknown

hadoop@hive:~$ hadoop-2.7.3/bin/hdfs namenode -format
hadoop@hive:~$ hadoop-2.7.3/sbin/start-dfs.sh 
Starting namenodes on [localhost]
localhost: starting namenode, logging to /home/hadoop/hadoop-2.7.3/logs/hadoop-hadoop-namenode-hive.out
localhost: starting datanode, logging to /home/hadoop/hadoop-2.7.3/logs/hadoop-hadoop-datanode-hive.out
Starting secondary namenodes [0.0.0.0]
0.0.0.0: starting secondarynamenode, logging to /home/hadoop/hadoop-2.7.3/logs/hadoop-hadoop-secondarynamenode-hive.out

成功启动后，可访问web界面查看nameNode和datanode信息以及HDFS中的文件。

伪分布式启动 YARN为可选操作，启动后可以通过web界面查看任务运行情况

hadoop@hive:~$ hadoop-2.7.3/sbin/start-yarn.sh 
starting yarn daemons
starting resourcemanager, logging to /home/hadoop/hadoop-2.7.3/logs/yarn-hadoop-resourcemanager-hive.out
localhost: starting nodemanager, logging to /home/hadoop/hadoop-2.7.3/logs/yarn-hadoop-nodemanager-hive.out
root@hive:/home/hadoop# jps
5366 ResourceManager
5014 DataNode
4904 NameNode
7354 Jps
5214 SecondaryNameNode
7055 RunJar

监听端口

解压Hive安装包，配置运行环境变量

hadoop@hive:~$ tar xvf apache-hive-2.1.0-bin.tar.gz
hadoop@hive:~$ tail -3 .bash_profile 
export HADDOP_HOME=/home/hadoop/hadoop-2.7.3/
export HIVE_HOME=/home/hadoop/apache-hive-2.1.0-bin/
export PATH=$PATH:$HADDOP_HOME/bin:$HADDOP_HOME/bin:$HIVE_HOME/bin
hadoop@hive:~$ source !$
source .bash_profile

HDFS上创建目录并设置权限

hadoop@hive:~$ hadoop fs -mkdir -p /tmp
hadoop@hive:~$ hadoop fs -mkdir -p /user/hive/warehouse
hadoop@hive:~$ hadoop fs -chmod g+w /tmp
hadoop@hive:~$ hadoop fs -chmod g+w /user/hive/warehouse

初始化数据库

hadoop@hive:~$ schematool -dbType derby -initSchema
SLF4J: Class path contains multiple SLF4J bindings.
..........
Starting metastore schema initialization to 2.1.0
Initialization script hive-schema-2.1.0.derby.sql
