I have found answer on the forum.

Hello,
Yes, this ‘error’ is a little misleading. It is just that the version of
logrotate on RHEL/CentOS 6 does not support the ‘su’ directive, whereas in
7, we must have it.
However, this should not cause it to return a value other than 0 when
reloading Apache and is therefore, probably not the problem.
What is the return code from the logrotate command? verify with:
echo $?
You can also comment out the lines with the ‘su’ directive in
/etc/logrotate.d/kaltura_apache just to reduce noise.
May the source be with you,
Jess Portnoy
