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.
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?
