Hi,
@EVENTS_LOGS_DIR@ should be replaced in /opt/kaltura/dwh/.kettle/kettle.properties with the value /opt/kaltura/web/logs
This is done as part of the /opt/kaltura/bin/kaltura-base-config.sh if you're using RPM or in /var/lib/dpkg/info/kaltura-base.postinst on deb.
You can do it manually if you'd like but I am somewhat concerned that if you're missing this value, you might have additional place holders that were never replaced.
Best thing to do would probably be re-running the config scripts but if this is truly the only issue, you can try to manually replace this as a first step.
