本文介紹brew install hive並修改預設的metastore儲存方案，改Derby資料庫為mysql的方法以及可能遇到的問題的解決方案。

1. 通過homebrew安裝hive

1	brew install hive

2. 新增hadoop和hive的環境變數

1 2 3 4 5 6

sudo vim ~/.bash_profile export HADOOP_HOME=/usr/local/Cellar/hadoop/hadoop export HIVE_HOME= /usr/local/Cellar/hive/hive/libexec source ~/.bash_profile

3. 下載mysql connector

4. 建立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的配置檔案

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/libexec/conf cp hive-default.xml.template hive-site.xml #新增或者編輯如下內容 <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. 測試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. 在配置完成後，可能遇到的問題解決方案： 一，Reference error 解決方案：         使用sequel pro， 修改hive使用者的許可權，新增Reference的global許可權。 二，啟動hive時遇到的" Caused by: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D " 解決方案： 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
