After some period of time your oozie db will be big and it may start throwing space issue or might be some slowness during oozie UI load. There are some properties which will help you to purge your oozie data but sometime, the oozie purge service does not function as expected. It result to a huge oozie database size which leads to slowdown your oozie UI.
To reduce size of the tables, you can run the below query to delete some old historical records:
- Backup the database (highly recommend).
mysqldump -u root -p oozie > /tmp/oozie.sql
- Login to the oozie database.
mysql -u root -p <password>
- Run the below queries to clean up the historical records old than specific date (please adjust the date accordingly):
DELETE FROM OOZIE.WF_ACTIONS where WF_ID IN (SELECT ID from OOZIE.WF_JOBS where end_time < timestamp('2015-09-01 00:00:00')); DELETE FROM oozie.wf_jobs where end_time < timestamp('2015-09-01 00:00:00'); DELETE from oozie.coord_actions where JOB_ID in (select ID from oozie.coord_jobs where END_TIME < timestamp('2015-09-01 00:00:00')); DELETE from oozie.coord_jobs where END_TIME < timestamp('2015-09-01 00:00:00');
- If you are using mysql then run the following command to reduce the database size:
mysqlcheck -u root -p<password> -o oozie
And now you need to happy as you have purge old data in oozie db.
You also can update oozie configuration to auto purge:
oozie.service.PurgeService.coord.older.than = 7 oozie.service.PurgeService.bundle.older.than = 7 oozie.service.PurgeService.purge.limit = 100 oozie.service.PurgeService.older.than = 7 oozie.service.PurgeService.purge.interval = 3600 oozie.service.PurgeService.purge.old.coord.action = true
