mac OSX 上 brew install hive

Posted 2020-07-03 会当临绝顶，一览众山小

本文介绍brew install hive并修改默认的metastore存储方案，改Derby数据库为mysql的方法以及可能遇到的问题的解决方案。

1. 通过homebrew安装hive

1	brew install hive

2. 添加hadoop和hive的环境变量

1 2 3 4 5 6

sudo vim ~/.bash_profile   export HADOOP_HOME=/usr/local/Cellar/hadoop/hadoop.version.no export HIVE_HOME=/usr/local/Cellar/hive/hive.version.no/libexec   source ~/.bash_profile

3. 下载mysql connector

1 2 3

curl -L ‘http://www.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.22.tar.gz/from/http://mysql.he.net/‘ | tar xz   sudo cp mysql-connector-java-5.1.15/mysql-connector-java-5.1.22-bin.jar /usr/local/Cellar/hive/hive.version.no/libexec/lib/

4. 创建mysql metastore

1 2 3 4

mysql> CREATE DATABASE metastore; mysql> USE metastore; mysql> CREATE USER ‘hiveuser‘@‘localhost‘ IDENTIFIED BY ‘password‘; mysql> GRANT SELECT,INSERT,UPDATE,DELETE,ALTER,CREATE ON metastore.* TO ‘hiveuser‘@‘localhost‘;

5. 配置hive的配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

cd /usr/local/Cellar/hive/hive.version.no/libexec/conf cp hive-default.xml.template hive-site.xml   #添加或者编辑如下内容 <property>   <name>javax.jdo.option.ConnectionURL</name>   <value>jdbc:mysql://localhost/metastore</value> </property> <property>   <name>javax.jdo.option.ConnectionDriverName</name>   <value>com.mysql.jdbc.Driver</value> </property> <property>   <name>javax.jdo.option.ConnectionUserName</name>   <value>hiveuser</value> </property> <property>   <name>javax.jdo.option.ConnectionPassword</name>   <value>password</value> </property> <property>   <name>datanucleus.fixedDatastore</name>   <value>false</value> </property>

6. 测试hive是否工作

1 2 3

$ hive; hive > show tables; hive> create table temp_table temp_col string;

7. Revoke few permissions on the mysql metastore

1 2	$ mysql mysql> REVOKE ALTER,CREATE ON metastore.* FROM ‘hiveuser‘@‘localhost‘;

9. Further troubleshooting : 
(a) If you get a bin log error saying statement format is not support. Login to your mysql console as root

$ mysql -uroot
mysql > SET GLOBAL binlog_format = ‘ROW‘;

(b) You could also try reading the logs as follows. Logs can be emitted to the bash prompt while running hive by setting hive.root.logger to INFO,console.

$ hive -hiveconf hive.root.logger=INFO,console

(c)You could also read the raw hive logs which is usually located at /tmp/user_name/hive.log

 

(d)If you still have any errors, feel free to comment.

 

 

在配置完成后，可能遇到的问题解决方案：

一，Reference error

解决方案：

        使用sequel pro， 修改hive用户的权限，添加Reference的global权限。

 

二，启动hive时遇到的" Caused by: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D "

 

解决方案：

 

修改hive-site.xml 配置中的以下key value即可：

 

<name>hive.exec.scratchdir</name>

<value>/tmp/hive-${user.name}</value>

 

 <name>hive.exec.local.scratchdir</name>

 <value>/tmp/${user.name}</value>

 

<name>hive.downloaded.resources.dir</name>

<value>/tmp/${user.name}_resources</value>

 

<name>hive.scratch.dir.permission</name>

    <value>733</value>

 

restart hive metastore and hiveserver2
