Oozie Log Overview¶
Log Description¶
Log path: The default storage paths of Oozie log files are as follows:
Run log: /var/log/Bigdata/oozie
Audit log: /var/log/Bigdata/audit/oozie
Log archiving rule: Oozie logs are classified into run logs, script logs, and audit logs. The maximum size of a run log file is 20 MB, and a maximum of 20 run log files can be reserved. The maximum size of an audit log file is 20 MB, and a maximum of 20 audit log files can be reserved.
Note
A compressed log file is generated for oozie.log every hour. 720 compressed files (log files of one month) are retained by default.

Log Level¶
Table 2 describes the log levels provided by Oozie.
The priorities of log levels are ERROR, WARN, INFO, and DEBUG in descending order. Logs whose levels are higher than or equal to the set level are printed. The number of printed logs decreases as the configured log level increases.
Level | Description |
|---|---|
ERROR | Logs of this level record abnormal information about events that cause process exceptions. |
WARN | Logs of this level record exception information about the current event processing. |
INFO | Logs of this level record normal running status information about the system and events. |
DEBUG | Logs of this level record system information and information about database underlying data transmission. |
To modify log levels, perform the following operations:
Log in to FusionInsight Manager.
Choose Cluster > Name of the desired cluster > Services > Oozie > Configurations.
Select All Configurations.
On the menu bar on the left, select the log menu of the target role.
Select a desired log level.
Click Save, and then click OK. The settings take effect after the processing is complete.
