Hive Learning (5) hive logs

Logs record the process of running the program and are a powerful tool for finding problems.

There are two types of logs in hive:
1. the system log records the hive running status and error status.
2. The job log records the historical execution process of jobs in hive.

Where are system logs stored?
The storage of hive logs is recorded in the hive/CONF/hive-log4j.properties file,
Default storage:

Hive. Root. Logger = warn, drfa
Hive. log. dir =/tmp/$ {user. name} # default storage location
Hive. log. File = hive. log # default file name

Where are job logs stored?

// Location of hive run time structured Log File
Hivehistoryfileloc ("hive. querylog. Location", "/tmp/" + system. getproperty ("user. Name ")),

Stored in the directory/tmp/{user. name} by default.
