[会装]Hive安装（基于mysql数据库）

环境信息：Mac

安装步骤：

1. 下载hive组件（我选择的是社区的2.0.1版本）

　　http://apache.mirror.globo.tech/hive/hive-2.0.1/

2. 下载mysql驱动

　　https://dev.mysql.com/downloads/connector/j/

3. 设定环境变量（至于具体放到什么文件夹可以自由指定这里不做赘述）

export CATALINA_HOME=/Users/apple/Desktop/software/apache-tomcat-8.5.11
export KYLIN_HOME=/Users/apple/Desktop/hadoop2/apachesrc/kylin/bin/apache-kylin-1.6.0-cdh5.7-bin
#hadoop config
#export DERBY_HOME=/Users/apple/Desktop/hadoop2/tools/db-derby-10.4.2.0-bin
export HIVE_HOME=/Users/apple/Desktop/hadoop2/apachesrc/hive/2.0.1/bin/apache-hive-2.0.1-bin
export HIVE_CONF_DIR=/Users/apple/Desktop/hadoop2/apachesrc/hive/2.0.1/bin/config
export HCAT_HOME=$HIVE_HOME/hcatalog
export HIVE_CONF=/Users/apple/Desktop/hadoop2/apachesrc/hive/2.0.1/bin/config
export HADOOP_HOME=/Users/apple/Desktop/hadoop2/cdh/hadoop/bin/hadoop-2.6.0-cdh5.4.2
export HADOOP_CONF_DIR=/Users/apple/Desktop/hadoop2/cdh/hadoop/bin/config
export HBASE_HOME=/Users/apple/Desktop/hadoop2/cdh/hbase/bin/hbase-1.0.0-cdh5.4.2
export HBASE_CONF_DIR=/Users/apple/Desktop/hadoop2/cdh/hbase/bin/config
export PATH=$HIVE_HOME/bin:$HBASE_HOME/bin:$KYLIN_HOME/bin:$HCAT_HOME/bin:$CATALINA_HOME/bin:$SBT_HOME/bin:$MAVEN_HOME/bin:$PROTOBUF_HOME/bin:$JAVA_HOME/bin:$ANT_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

4.修改(增加)hive配置文件

　　修改$HIVE_CONF/hive_site.xml,加入：

  <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.ConnectionDriverName</name>
    <value>com.mysql.jdbc.Driver</value>
    <description>Driver class name for a JDBC metastore</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionUserName</name>
    <value>mysql</value>
    <description>Username to use against metastore database</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>mysql</value>
    <description>password to use against metastore database</description>
  </property>

<name>hive.metastore.warehouse.dir</name>

<value>/hive/warehouse</value>

<description>location of default database for the warehouse</description>

</property>

　　在$HIVE_CONF文件夹下创建jpox.properties文件输入：

javax.jdo.PersistenceManagerFactoryClass =

org.jpox.PersistenceManagerFactoryImpl
org.jpox.autoCreateSchema = false
org.jpox.validateTables = false
org.jpox.validateColumns = false
org.jpox.validateConstraints = false
org.jpox.storeManagerType = rdbms
org.jpox.autoCreateSchema = true
org.jpox.autoStartMechanismMode = checked
org.jpox.transactionIsolation = read_committed
javax.jdo.option.DetachAllOnCommit = true
javax.jdo.option.NontransactionalRead = true
javax.jdo.option.ConnectionDriverName = com.mysql.jdbc.Driver
javax.jdo.option.ConnectionURL = jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true
javax.jdo.option.ConnectionUserName = mysql
javax.jdo.option.ConnectionPassword = mysql
~

5. 将mysql驱动拷贝到hive的lib目录中

　　mysql-connector-java-5.1.41-bin.jar

5. 初始化memstore数据库：

schematool -initSchema -dbType mysql

6. 创建hive工作目录：　　

$ $HADOOP_HOME/bin/hadoop fs -mkdir /tmp 
$ $HADOOP_HOME/bin/hadoop fs -mkdir /hive/warehouse
$ $HADOOP_HOME/bin/hadoop fs -chmod g+w /tmp 
$ $HADOOP_HOME/bin/hadoop fs -chmod g+w /hive/warehouse

7.输入hive：

Logging initialized using configuration in jar:file:/Users/apple/Desktop/hadoop2/apachesrc/hive/2.0.1/bin/apache-hive-2.0.1-bin/lib/hive-common-2.0.1.jar!/hive-log4j2.properties
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. tez, spark) or using Hive 1.X releases.
hive> show tables;
OK
