Hive编程(十二)【开发】

12.1 修改Log4J属性

Hive使用$HIVE_HOME/conf目录下的2个Log4j配置文件来配置日志。hive-log4j.properties文件控制CLI和其他本地执行组件的日子。hive-exec-log4j.properties控制MapReduce tasks内的日志。

使用hiveconf修改Hive日志级别

$ bin/hive -hiveconf hive.root.logger=DEBUG,console 

12/03/27 08:46:01 WARN conf.HiveConf: hive-site.xml not found on CLASSPATH 

12/03/27 08:46:01 DEBUG conf.Configuration: java.io.IOException: config() 

12.2 连接Java调试器到Hive

$ bin/hive --help --debug 

Allows to debug Hive by connecting to it via JDI API 

Usage: hive --debug[:comma-separated parameters list] 

Parameters: 

recursive= Should child JVMs also be started in debug mode. Default: y 

port= Port on which main JVM listens for debug connection. Defaul... 

mainSuspend= Should main JVM wait with execution for the debugger to con... 

childSuspend= Should child JVMs wait with execution for the debugger to c... 

swapSuspend Swaps suspend options between main and child JVMs 

12.3 从源码编译Hive

12.3.2 执行hook

12.4 配置Hive和Eclipse

12.5 Maven工程中使用Hive
