Category : Hive
Many time we see that during troubleshoot we do not find much information if we are just default logger. So no worries I will help you to guide how to enable debug mode in logs or on your console.
Case 1: Use the following command to start hive: Set follwoing property to turn on debug mode on console.
hive -hiveconf hive.root.logger=ALL,console
It will log all messages to console.
Case 2: In case if you want to write you log in log file only for each and every steps which user or job does then you can use following process.
- Login to Ambari portal and click on Hive service.
- Goto config and search for hive.root.logger string in search box.
- Once you will then you need to change default value(hive.root.logger=INFO,DFRA) to hive.root.logger=DEBUG,DFRA
Note: It may fill your log dir soon so please keep deleting old file or keep maintain log dir.
