Hello,

My guess would be permission issues. Note that the cron jobs for dwh run as the kaltura user and need to be able to write to certain directories.
If you review the logs under /opt/kaltura/dwh/logs, I’m pretty sure you’ll find exactly what directory is attempted to be written to.
You can also try to run:
# /opt/kaltura/bin/kaltura-run-dwh.sh
as root and check whether that succeeds, if so, then it is certainly a permissions issue.
