Mac 安装Hive

Mac 安装Hive

1. 用brew安装

brew install hive

2. mysql中创建元数据库

安装mysql，执行下面命令

create database metastore; create user 'hive'@'localhost' identified by '123456'; grant select,insert,update,delete,alter,create,index,references on metastore.* to 'hive'@'localhost'; flush privileges;

3. 创建修改配置

在libexec/conf 中，把hive-default.xml.template 复制一份重新命名为hive-site.xml

javax.jdo.option.ConnectionURL jdbc:mysql://localhost/metastore javax.jdo.option.ConnectionDriverName com.mysql.cj.jdbc.Driver javax.jdo.option.ConnectionUserName hive(填上述mysql中创建的用户名) javax.jdo.option.ConnectionPassword 123456(填上述mysql中创建的用户密码) hive.exec.local.scratchdir /tmp/hive hive.querylog.location /tmp/hive hive.downloaded.resources.dir /tmp/hive hive.server2.logging.operation.log.location /tmp/hive

4. 去网站下载mysql的connect jar 复制到lib中

mac 的选择这个independent，解压后把jar复制到libexec/lib 中

5. 环境变量设置

export ANDROID_HOME=~/Library/Android/sdk # added by Anaconda3 5.1.0 installer export PATH="/Users/walle/anaconda3/bin:$PATH" #sqoop export SQOOP_HOME=/usr/local/Cellar/sqoop/1.4.6/libexec export PATH=$PATH:$SQOOP_HOME/bin # hadoop export HADOOP_HOME=/usr/local/Cellar/hadoop/3.1.0/libexec export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin #hive export HIVE_HOME=/usr/local/Cellar/hive/hive/2.3.1/libexec export PATH=$PATH:$HIVE_HOME/bin export PATH=$PATH:/Applications/XAMPP/xamppfiles/bin for f in $HADOOP_HOME/share/hadoop/common/hadoop-*.jar;do export CLASSPATH=$CLASSPATH:$f done for f in $HADOOP_HOME/share/hadoop/hdfs/hadoop-*.jar;do export CLASSPATH=$CLASSPATH:$f done for f in $HADOOP_HOME/share/hadoop/mapreduce/hadoop-*.jar;do export CLASSPATH=$CLASSPATH:$f done for f in $HADOOP_HOME/share/hadoop/yarn/hadoop-*.jar;do export CLASSPATH=$CLASSPATH:$f done export CLASSPATH=$CLASSPATH:$HADOOP_HOME/share/common/lib:$HADOOP_HOME/share/hdfs/lib:$HADOOP_HOME/share/mapreduce/lib:$HADOOP_HOME/share/tools/lib:$HADOOP_HOME/share/yarn/lib

6. 初始化库

在bin目录下执行下面的初始化

schematool -initSchema -dbType mysql

7. 运行hive
