ubuntu16.04搭建Hadoop2.7.2+spark1.6.1+mysql+hive2.0.0伪分布学习环境

按步骤走就行：

（1）raini@biyuzhe:~$ gedit .bashrc

#java
export JAVA_HOME=/home/raini/app/jdk1.7.0_79
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH
export PATH=${JAVA_HOME}/bin:$JRE_HOME/bin:$PATH

#scala
export SCALA_HOME=/home/raini/app/scala-2.10.6
export PATH=${SCALA_HOME}/bin:$PATH

#spark
export SPARK_HOME=/home/raini/spark1
export PATH=$PATH:$SPARK_HOME/bin:$PATH

# hadoop2.6
export HADOOP_PREFIX=/home/raini/hadoop2
export CLASSPATH=".:$JAVA_HOME/lib:$CLASSPATH"
export PATH="$JAVA_HOME/:$HADOOP_PREFIX/bin:$PATH"
export HADOOP_PREFIX PATH CLASSPATH


（2）raini@biyuzhe:~$ sudo apt-get install rsync

（3）raini@biyuzhe:~$ sudo apt-get install openssh-server

cd ~/.ssh/   # 若没有该目录，请先执行一次ssh localhost
ssh-keygen -t rsa   # 会有提示，都按回车就可以
cat id_rsa.pub >> authorized_keys  # 加入授权
使用ssh localhost试试能否直接登录

（4）raini@biyuzhe:~$ sudo gedit /etc/hosts

127.0.0.1    localhost
127.0.1.1    biyuzhe
#10.155.243.206  biyuzhe
#有的说这里必须修改，否则后面会遇到连接拒绝等问题

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

（5）修改配置文件：etc/hadoop/hadoop-env.sh

    export JAVA_HOME=/home/raini/app/jdk
    export HADOOP_COMMON_HOME=/home/raini/hadoop

（6）raini@biyuzhe:~$ gedit .bashrc

    添加export PATH="/home/raini/hadoop/bin:/home/raini/hadoop/sbin:
    如  export PATH="/home/raini/hadoop/bin:/home/raini/hadoop/sbin:   $JAVA_HOME/:$HADOOP_PREFIX/bin:$PATH"

（7）修改文件etc/hadoop/core-site.xml


   
        hadoop.tmp.dir
        file:/home/raini/hadoop/tmp
        Abase for other temporary directories.
   
   
        fs.defaultFS
        hdfs://localhost:9000
   
 
      io.file.buffer.size

       hadoop.proxyuser.master.hosts
        *
  
  
       hadoop.proxyuser.master.groups
       *
  



（8）修改etc/hadoop/hdfs-site.xml:


 
 
    
            dfs.namenode.name.dir
            file:/home/raini/hadoop/tmp/dfs/namenode
    
    
            dfs.datanode.data.dir

            dfs.replication
            1
    
 
    
            dfs.webhdfs.enabled
            true
    



（9）修改配置文件mapred-site.xml



   
          mapreduce.framework.name
          yarn
   

   
          mapreduce.jobhistory.address
          localhost:10020
   

    
          mapreduce.jobhistory.webapp.address
          localhost:19888
    




（10）修改配置文件yarn-site.xml

 



   
      yarn.nodemanager.aux-services
      mapreduce_shuffle
   

   
      yarn.nodemanager.aux-services.mapreduce.shuffle.class
      org.apache.hadoop.mapred.ShuffleHandler
   

   
       yarn.resourcemanager.address
       localhost:8032
   

   
         yarn.resourcemanager.scheduler.address
         localhost:8030
   

   
         yarn.resourcemanager.resource-tracker.address

--------------------------------spark安装

（2）配置Spark环境变量

export SPARK_HOME=/home/raini/spark
export PATH=${SPARK_HOME}/bin:$PATH

（3）配置spark-env.sh
export JAVA_HOME=/home/raini/app/jdk
export SCALA_HOME=/home/raini/app/scala
export SPARK_WORKER_MEMORY=4g
export SPARK_MASTER=biyuzhe
export SPARK_MASTER_PORT=7077

（4）cp slaves.template slaves

#localhost
biyuzhe

spark/sbin/start-all.sh 启动

- -----------------------mysql----Hive2.0.0安装

1）mysql安装

$sudo apt-get install mysql-server

登录mysql：$mysql -u root -p

建立数据库hive：mysql>create database hive;

                mysql>show databases;//查看创建；

这里一定要把hive数据库的字符集修改为latin1，而且一定要在hive初次启动的时候就修改字符集 （否则就等着删除操作的时候死掉吧）
                 mysql>alter database hive character set latin1;

创建hive用户,并授权：mysql>grant all on hive.* to hive@'%'  identified by 'hive';

（法二： DROP USER 'hive'@'%';

         mysql> create user 'hive'@'%' identified by 'hive';
       赋予权限  grant all privileges on *.* to 'hive'@'%' with grant option;

     ）

更新：mysql>flush privileges;

 查询mysql的版本：mysql>select version();//这里是5.7.11-0ubuntu6

下载mysql的JDBC驱动包： http://dev.mysql.com/downloads/connector/j/

下载mysql-connector-java-5.1.38.tar.gz ，复制msyql的JDBC驱动包到Hive的lib目录下。

2）Hive安装

官网http://hive.apache.org/下载apache-hive-2.0.0-bin.tar.gz并解压在home/hp路径下。

环境配置

添加如下：
#Hive
export HIVE_HOME=/home/raini/app/hive-2.0.0
export PATH=$PATH:${HIVE_HOME}/bin
export CLASSPATH=$CLASSPATH.:{HIVE_HOME}/lib

配置hive-env.sh文件

复制hive-env.sh.template，修改hive-env.sh文件

指定HADOOP_HOME及HIVE_CONF_DIR的路径如下：

HADOOP_HOME=/home/。。/hadoop

export HIVE_CONF_DIR=/home/。。/hive/conf

# export HADOOP_HEAPSIZE=512

# 含有额外的图书馆为蜂巢编译/执行必需的文件夹
# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=/home/raini/app/hive-2.0.0/lib


4）配置hive-site.xml文件

      Hive uses Hadoop, so:
 
    you must have Hadoop in your path OR
    export HADOOP_HOME=
 
In addition, you must create /tmp and /user/hive/warehouse (aka hive.metastore.warehouse.dir) and set them chmod g+w in HDFS before you can create a table in Hive.
 
Commands to perform this setup（需要给755权限）:

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

raini@biyuzhe:~$ hadoop fs -chmod g+w   /user/hive/log
raini@biyuzhe:~$ hadoop fs -chmod g+w   /user/hive/warehouse    /usr/hive/tmp

You may find it useful, though it's not necessary, to set HIVE_HOME:
 
  $ export HIVE_HOME=
    export HIVE_HOME=/home/raini/app/hive

$ sudo /etc/init.d/mysql status

hive/bin下要有->mysql-connector-java-5.1.38-bin.jar

（ 5）hive配置－设置hive数据将元数据存储在MySQL中 ， hive需要将元数据存储在RDBMS中，默认情况下，配置为Derby数据库

   hive.metastore.local
   true
  使用本机mysql服务器存储元数据。这种存储方式需要在本地运行一个mysql服务器



   javax.jdo.option.ConnectionURL
   jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true
   biyuzhe使用的数据库?charcherEncoding=UTF-8



   javax.jdo.option.ConnectionDriverName
   com.mysql.jdbc.Driver
   使用的链接方式



   javax.jdo.option.ConnectionUserName
   hive
   mysql用户名



   javax.jdo.option.ConnectionPassword
   hive



  hive.metastore.warehouse.dir
  /user/hive/warehouse
  元数据存放的地放，需要在本地（不是hdfs中）新建这个目录



    hive.exec.scratdir
    /user/hive/tmp
    hive的数据临时文件目录，需要在本地新建这个目录HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/<username> is created, with ${hive.scratch.dir.permission}.
 


    hive.querylog.location
    /user/hive/log
    这个是用于存放hive相关日志的目录



    hive.cli.print.current.db
    true

-------------------------------------------finish hive-site.xml

cp hive-log4j.properties.template  hive-log4j.proprties

vi hive-log4j.properties

hive.log.dir=

这个是当hive运行时，相应的日志文档存储到什么地方

（mine：hive.log.dir=/usr/hive/log/${user.name}）

hive.log.file=hive.log

这个是hive日志文件的名字是什么

默认的就可以，只要您能认出是日志就好，

只有一个比较重要的需要修改一下，否则会报错。

log4j.appender.EventCounter=org.apache.hadoop.log.metrics.EventCounter

如果没有修改的话会出现：

WARNING: org.apache.hadoop.metrics.EventCounter is deprecated.

please use org.apache.hadoop.log.metrics.EventCounter  in all the  log4j.properties files.

（只要按照警告提示修改即可）。

-------------------------------------------------------finish all

hive metastore 服务端启动命令：
hive --service metastore -p

raini@biyuzhe:~/app/hive/tmp$ hive --service metastore > /tmp/hive_metastore.log 2>&1 &
[1] 26856

这里Hive中metastore（元数据存储）采用Local方式，非remote方式。

报错：
    Exception in thread "main" java.lang.RuntimeException: Hive metastore database is not initialized. Please use schematool (e.g. ./schematool -initSchema -dbType ...) to create the schema. If needed, don't forget to include the option to auto-create the underlying database in your JDBC connection string (e.g. ?createDatabaseIfNotExist=true for mysql)


第一次需执行初始化命令$raini@biyuzhe:~$ schematool -dbTypemysql –initSchema
raini@biyuzhe:~$ schematool -initSchema -dbType mysql -userName=hive -passWord=hive



查看初始化后信息$ schematool -dbType mysql –info

启动Hadoop服务：$sbin/start-dfs.sh和$sbin/start-yarn.sh

启动raini@biyuzhe:~/app$ hive
