["Gézapeti (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-3585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17046514#comment-17046514 ] 

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?
