could you help us with a problem regarding the /var/log directory
at certain times (we couldn't identify the right moment) the /var/log directory is changing the permissions to 750 and with that the CDH 6.3.x cluster services is failing because it can't write the logs.
Have you ever had a problem like this? did you manage to solve it?
we had to leave a crontab running every 5 minutes to always change it to 755.
