Transpatent Huge Page in Centos/Redhat

ronnie10 — Fri, 30 Mar 2018 07:23:27 GMT

Hi there,

Whenever instaling Cloudera on Redhat 7 or Centos 7, after disabling the transparent hugepage, the warning still showing, I have already put the following lines to /etc/rc.local, however it is still the same.

echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled

I tried the following as well.

echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled

Thank you.

after changing the rc.local to executable, it solved the issue

$chmod +x /etc/rc.d/rc.local
