1 Hive 运行日志配置

[hadoop@node1 ~]$ cd $HIVE_HOME/conf
[hadoop@node1 conf]$ ll
total 20
-rw-r--r--. 1 hadoop hadoop 1196 Mar 24  2016 beeline-log4j.properties.template
-rw-r--r--. 1 hadoop hadoop 2470 Jan 16 12:36 hive-env.sh
-rw-r--r--. 1 hadoop hadoop 2662 Mar 24  2016 hive-exec-log4j.properties.template
-rw-r--r--. 1 hadoop hadoop 3505 Mar 24  2016 hive-log4j.properties.template
-rw-rw-r--. 1 hadoop hadoop  938 Jan 16 15:36 hive-site.xml
[hadoop@node1 conf]$ cp hive-log4j.properties.template hive-log4j.properties

• hive-log4j.properties

hive.log.dir=/home/hadoop/appsData/hivelogs

2 Hive 属性配置

hive > set

...........
system:sun.java.launcher=SUN_STANDARD
system:sun.jnu.encoding=UTF-8
system:sun.management.compiler=HotSpot 64-Bit Tiered Compilers
system:sun.os.patch.level=unknown
system:user.country=US
system:user.dir=/home/hadoop
system:user.home=/home/hadoop
system:user.language=en
system:user.name=hadoop
system:user.timezone=Asia/Shanghai

3 Hive 常见属性配置

3.1 Hive 数据仓库的位置

• default : /user/hive/warehouse

- 在仓库目录下，没有对默认的数据库 default 创建文件夹
- 如果某张表属于 default 数据库，直接在数据仓库目录下创建一个文件夹

3.2 Hive 运行日志信息

• hive-log4j.properties

3.3 在 CLI 命令行上显示当前数据库，以及查询表的信息

• hive-site.xml

<property>
	<name>hive.cli.print.header</name>
	<value>true</value>
</property>

<property>
	<name>hive.cli.print.current.db</name>
	<value>true</value>
</property>

3.4 hive 启动时参数的设置

hive -help

[hadoop@node1 ~]$ hive -help
