Gézapeti commented on OOZIE-3585:
---------------------------------
Yes, log streaming in HA setup is an expensive operation for Oozie. It's
usually not a problem as it's mainly used for debugging errors and it's not
impacting general performance.
Do you have a different solution to the problem in mind?
