Analytics data not showing/visible

Can you change:

00 10 * * * kaltura /opt/kaltura/app/alpha/scripts/dwh/dwh_plays_views_sync.sh >> /opt/kaltura/log/cron.log

to read:
`
00 10 * * * kaltura /opt/kaltura/app/alpha/scripts/dwh/dwh_plays_views_sync.sh >> /opt/kaltura/log/cron.log 2>&1

?
this would also redirect output sent to STDERR to /opt/kaltura/log/cron.log. Perhaps there are errors during the execution when it's done by crond
