In a typical installation process, socket's somax
connection must NOT be set to a very low value (default is 128, which is very low for Hadoop
systems). Cloudera recommends that you set socket's somax connection value to atleast 16000
OOTB via Cloudera Manager or host inspector.
caution
Cloudera recommends to disable
fapolicyd daemon present in RHEL 8 (and later) systems before beginning
installation of Cloudera Manager application. Be informed that fapolicyd is a
user space daemon that determines access rights to files based on attributes of the process

with caution with enforcing the use of this daemon. Improper configuration may render the
system non-functional.

Kerberos form the baseline for secure operations of your CDP Runtime environment. Cloudera
supports security services such as Ranger and Atlas only
