error creating output file /etc/columnstore/Columnstore.xml-20200701: Permission denied

I got this message from the system:

/etc/cron.daily/logrotate:
error: error creating output file /etc/columnstore/Columnstore.xml-20200701: Permission denied

the directory /etc/columnstore has drwxr-xr-t. 2 root root 4096 30. Jun 20:59 columnstore

I am running the VirtualBox VM on CentOS7 as root.

What is this log rotation about? Which privileges does the directory need?
