Commands to disable hugepage on linux at host registration

Commands to disable hugepage on linux at host registration

Contributor

In the registration hosts during install HDP cluster, there is warning about hugepage is enbaled on all hosts.

However, only when I install CDH 5, I found these 2 commands provided to disable hugepage on linux

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

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

they commended to add to /etc/rc.d/, so every time it is up after reboot.

thanks,

Robin

yes, this link provide exact the same commands. however, do you think Hortonworks better have these commands in the Ambari installation. instead gave a warning and having installer to check all over the places to find out?
