Hive0.10.0安裝和配置

一.安裝
1.下載http://apache.fayea.com/apache-mirror/hive/hive-0.10.0/hive-0.10.0.tar.gz
2.解壓到當前用戶的hive目錄下：tar -zxvf hive-0.10.0.tar.gz /home/long1657/hive
3.配置環境變量：vim ~/.bashrc
export HIVE_HOME=/home/long1657/hive/hive-0.10.0
export PATH=$PATH:$HIVE_HOME/bin
source ~/.bashrc
4.把hive/conf目錄下的四個文件重命名：
mv hive-default.xml.template hive-site.xml
mv hive-env.sh.template hive-env.sh
mv hive-exec-log4j.properties.template hive-exec-log4j.properties
mv hive-log4j.properties.template hive-log4j.properties
4.配置hive-env.sh
指定hive配置文件的路徑
export HIVE_CONF_DIR=/home/long1657/hive/hive-0.10.0/conf(你的hive配置文件路徑)
指定Hadoop路徑
HADOOP_HOME=/home/long1657/hadoop/hadoop-0.20.2（你的hadoop安裝目錄）
二.使用Derby數據庫的安裝方式  
 什麼是Derby安裝方式
Apache Derby是一個完全用java編寫的數據庫，所以可以跨平臺，但需要在JVM中運行
Derby是一個Open source的產品，基於Apache License 2.0分發
即將元數據存儲在Derby數據庫中，也是Hive默認的安裝方式
即：默認的hive-size.xml中的配置如下：
 <property>
  <name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:derby:;databaseName=metastore_db;create=true</value>
  <description>JDBC connect string for a JDBC metastore</description>
</property>
 
<property>
  <name>javax.jdo.option.ConnectionDriverName</name>
  <value>org.apache.derby.jdbc.EmbeddedDriver</value>
  <description>Driver class name for a JDBC metastore</description>
</property>
<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>APP</value>
  <description>username to use against metastore database</description>
</property>
 
<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>mine</value>
  <description>password to use against metastore database</description>
</property>
此時通過:hive命令
 WARNING: org.apache.hadoop.metrics.jvm.EventCounter is deprecated. Please use org.apache.hadoop.log.metrics.EventCounter in all the log4j.properties files.
Logging initialized using configuration in jar:file:/home/test/Desktop/hive-0.8.1/lib/hive-common-0.8.1.jar!/hive-log4j.properties
Hive history file=/tmp/test/hive_job_log_test_201208260529_167273830.txt
hive> show tables;
現實具體的表，上訴表示安裝成功。
三.使用MySQL數據庫作爲hive的metastore的安裝方式
通過第一個我們安裝好了hive
1.現在需要安裝mysql-server:
  sudo apt-get install mysql-server
2.安裝好登錄mysql:mysql -h localhost -u root -p
3.在mysql內創建hive的用戶：create user 'myHive'@'localhost' IDENTIFIED BY 'myHive';
4.給myHive授權:grant all privileges on *.* 'myHive'@'localhost' with grant option;
5.配置hive配置文件hive-site.xml:
<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
</property>

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

<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>myHive</value>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>myHive</value>
</property>
6.下載 mysql-connector-java-5.1.24-bin.jar，放到hive的lib目錄；
此時通過:hive命令
 WARNING: org.apache.hadoop.metrics.jvm.EventCounter is deprecated. Please use org.apache.hadoop.log.metrics.EventCounter in all the log4j.properties files.
Logging initialized using configuration in jar:file:/home/test/Desktop/hive-0.8.1/lib/hive-common-0.8.1.jar!/hive-log4j.properties
Hive history file=/tmp/test/hive_job_log_test_201208260529_167273830.txt
hive> show tables;
使用mysql作爲hive的matestore安裝完成！
