以下兩種方法都可以，推薦用方法一！

如果有誤，請見部落格

方法一：

　　步驟一： yum -y install mysql-server

　　步驟二：service mysqld start

　　步驟三：mysql -u root -p
　　Enter password: （預設是空密碼，按enter）

　　　　mysql > CREATE USER 'hive'@'%' IDENTIFIED BY 'hive';

　　　　mysql > GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION;

　　　　mysql > flush privileges;

　　　　mysql > exit;

　　步驟四：去hive的安裝目錄下的lib，下將 mysql-connector-java-5.1.21.jar 傳到這個目錄下。

　　步驟五：去hive的安裝目錄下的conf，下配置hive-site.xml

<property>

         <name>javax.jdo.option.ConnectionDriverName</name>

         <value>com.mysql.jdbc.Driver</value>

         <description>Driver class name for a JDBC metastore</description>

</property>

<property>

         <name>javax.jdo.option.ConnectionURL</name>

         <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>

         <description>JDBC connect string for a JDBC metastore</description>

</property>

<property>

         <name>javax.jdo.option.ConnectionUserName</name>

         <value>hive< /value>

         <description>Username to use against metastore database</description>

</property>

<property>

         <name>javax.jdo.option.ConnectionPassword</name>

         <value>hive< /value>

         <description>password to use against metastore database</description>

</property>

　　步驟六：切換到root使用者，配置/etc/profile檔案，source生效。
　　步驟七：OK成功！ 
　
　程式設計這一塊時，可以用自己的IP啦， 如  “jdbc:hive//192.168.80.128：10000/hivebase”

步驟二：　　

[[email protected] app]# service mysqld start
Initializing MySQL database: Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h HadoopSlave2 password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

[ OK ]
Starting mysqld: [ OK ]

　現在，到了這一步，不知道是哪裡出現錯誤！

 　　猜想一：是不是與hive 1.* 與 hive 0.*的版本，導致的問題？

　　 猜想二：是不是與HadoopSlave2的大寫有關，一般別人都是如，master、slave1、slave2等。

　　經過本人測驗 ，不是版本的問題，也不是大寫的問題。

　　對於，三點叢集，最好起名為，master、slave1、slave2

　　　　　五點叢集，最好起名為，master、slave1、slave2、slave3、slave4

　　　　  單點叢集，也最好起名為小寫！！！

 　　而是把， hdfs 寫成了 hfds。

[[email protected] hive-1.2.1]$

 　　參考： http://blog.csdn.net/jdplus/article/details/46493553

1.Delete jline from the Hadoop lib directory (it's only pulled in transitively from ZooKeeper).
2.export HADOOP_USER_CLASSPATH_FIRST=true

 　　接著，執行啊！

 　　參考：http://blog.csdn.net/zhumin726/article/details/8027802

　　　　　　http://blog.csdn.net/xgjianstart/article/details/52192879

解決方法：jline版本不一致，把HADOOP_HOME/share/hadoop/yarn/lib和HIVE_HOME/lib下的jline-**.jar版本一致就可以了，複製其中一個高版本覆蓋另一個。

　　即，取其中的高版本即可。

 

　　OK，啟動成功！

# Set HADOOP_HOME to point to a specific hadoop install directory
  export HADOOP_HOME=/home/hadoop/app/hadoop-2.6.0

# Hive Configuration Directory can be controlled by:
  export HIVE_CONF_DIR=/home/hadoop/app/hive-1.2.1/conf

# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
  export HIVE_AUX_JARS_PATH=/home/hadoop/app/hive-1.2.1/lib

　　再，儲存，用 source ./hive-env.sh(生效檔案)

在修改之前，要相應的建立目錄，以便與配置檔案中的路徑相對應，否則在執行hive時會報錯的。

mkdir -p /home/hadoop/data/hive-1.2.1/warehouse
mkdir -p /home/hadoop/data/hive-1.2.1/tmp
mkdir -p /home/hadoop/data/hive-1.2.1/log

<property>
<name>hive.metastore.warehouse.dir</name>
<value>/home/hadoop/data/hive-1.2.1/warehouse</value>
<description>location of default database for the warehouse</description>
</property>

<property>
<name>hive.exec.scratchdir</name>
<value>/home/hadoop/data/hive-1.2.1/tmp</value>
</property>

<property>
<name>hive.querylog.location</name>
<value>/home/hadoop/data/hive-1.2.1/log</value>
</property>

到此，hive-site.xml檔案修改完成!

　　然後在conf資料夾下，cp hive-log4j.properties.template  hive-log4j.proprties

開啟hive-log4j.proprties檔案，sudo gedit hive-log4j.proprties (Ubuntu系統裡)，若是CentOS裡，則 vim hive-log4j.properties

尋找hive.log.dir=
這個是當hive執行時，相應的日誌文件儲存到什麼地方

（      我的：    hive.log.dir=/home/hadoop/data/hive-1.2.1/log/${user.name}        ）

hive.log.file=hive.log
這個是hive日誌檔案的名字是什麼
預設的就可以，只要您能認出是日誌就好。

只有一個比較重要的需要修改一下，否則會報錯。

log4j.appender.EventCounter=org.apache.hadoop.log.metrics.EventCounter
如果沒有修改的話會出現：

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）。

至此，hive-log4j.proprties檔案修改完成。

　　接下來，是重頭戲！

　　接下來要配置的是以MySQL作為儲存元資料庫的hive的安裝(此中模式下是將hive的metadata儲存在mysql中，mysql的執行環境支撐雙向同步和叢集工作環境，這樣的話

，至少兩臺資料庫伺服器上匯備份hive的元資料)，要使用hadoop來建立相應的資料夾路徑，

並設定許可權：

bin/hadoop fs -mkdir /user/hadoop/hive/warehouse

bin/hadoop fs -mkdir /user/hadoop/hive/tmp

bin/hadoop fs -mkdir /user/hadoop/hive/log

bin/hadoop fs -chmod g+w /user/hadoop/hive/warehouse

bin/hadoop fs -chmod g+w /user/hadoop/hive/tmp

bin/hadoop fs -chmod g+w /user/hadoop/hive/log

繼續配置hive-site.xml

[1]

<property>
<name>hive.metastore.warehouse.dir</name>
<value>hdfs://localhost:9000/user/hadoop/hive/warehouse</value>

（這是單節點的）    　（我的是3節點叢集，在HadoopSlave1裡安裝的hive，所以是HadoopMaster，但是會報錯誤啊！）

　　　　（所以啊，若是單節點倒無所謂，若是跟我這樣，3節點啊，最好是HadoopMaster這臺機器上，安裝Hive啊！！！血淋淋的教訓）
(這裡就與前面的hadoop fs -mkdir -p /user/hadoop/hive/warehouse相對應)

（要麼，就是如在HadoopSlave1上，則為/home/hadoop/data/hive-1.2.1/warehouse）

</property>
其中localhost指的是筆者的NameNode的hostname；

[2]

<property>
<name>hive.exec.scratchdir</name>
<value>hdfs://localhost:9000/user/hadoop/hive/scratchdir</value>　　
</property>

[3]

//這個沒有變化與derby配置時相同
<property>
<name>hive.querylog.location</name>
<value>/usr/hive/log</value>
</property>
-------------------------------------

[4]

<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNoExist=true</value>  　　
</property>
javax.jdo.option.ConnectionURL
這個引數使用來設定元資料連線字串

注意紅字部分在hive-site.xml中是有的，不用自己新增。

我自己的錯誤：沒有在檔案中找到這個屬性，然後就自己添加了結果導致開啟hive一直報錯。最後找到了檔案中的該屬性選項然後修改，才啟動成功。

Unableto open a test connection to the given database. JDBC url =jdbc:derby:;databaseName=/usr/local/hive121/metastore_db;create=true,username = hive. Terminating connection pool (set lazyInit to true ifyou expect to start your database after your app). OriginalException: ------

-------------------------------------

[5]

<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
javax.jdo.option.ConnectionDriverName

關於在hive中用java來開發與mysql進行互動時，需要用到一個關於mysql的connector，這個可以將java語言描述的對database進行的操作轉化為mysql可以理解的語句。

connector是一個用java語言描述的jar檔案，而這個connector可以在官方網站上下載，經驗正是connector與mysql的版本號不一致也可以執行。

connector要copy到/usr/local/hive1.2.1/lib目錄下

[6]

<property>
<name>javax.jdo.option.ConnectorUserName</name>
<value>hive</value>
</property>
這個javax.jdo.option.ConnectionUserName
是用來設定hive存放元資料的資料庫(這裡是mysql資料庫)的使用者名稱稱的。

[7]

--------------------------------------
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
</property>
這個javax.jdo.option.ConnetionPassword是用來設定，
使用者登入資料庫（上面的資料庫）的時候需要輸入的密碼的.

[8]

<property>
<name>hive.aux.jars.path</name>
<value>file:///usr/local/hive/lib/hive-hbase-handler-0.13.1.jar,file:///usr/local/hive/lib/protobuf-java-2.5.0.jar,file:///us
r/local/hive/lib/hbase-client-0.96.0-hadoop2.jar,file:///usr/local/hive/lib/hbase-common-0.96.0-hadoop2.jar,file:///usr/local
/hive/lib/zookeeper-3.4.5.jar,file:///usr/local/hive/lib/guava-11.0.2.jar</value>
</property>

/相應的jar包要從hbase的lib資料夾下複製到hive的lib資料夾下。

[9]

<property>  
<name>hive.metastore.uris</name>  
<value>thrift://localhost:9083</value>  
</property>  
</configuration>

---------------------------------------- 到此原理介紹完畢

要使用Hadoop來建立相應的檔案路徑，
並且要為它們設定許可權：
bin/hadoop fs  -mkdir -p  /usr/hive/warehouse
bin/hadoop fs  -mkdir -p /usr/hive/tmp
bin/hadoop fs  -mkdir -p /usr/hive/log
bin/hadoop fs   -chmod g+w /usr/hive/warehouse
bin/hadoop fs   -chmod g+w /usr/hive/tmp
bin/hadoop fs   -chmod g+w /usr/hive/log
