Review request for Ambari and Dmitro Lisnichenko.
Bugs: AMBARI-5973
https://issues.apache.org/jira/browse/AMBARI-5973
Repository: ambari
Description
-------
We need to add checks for Transparent Huge Page. With it enabled, we have
pretty horrible performance, and it's enabled by default on RHEL.
Reference: <https://access.redhat.com/site/documentation/en-
US/Red_Hat_Enterprise_Linux/6/html/Performance_Tuning_Guide/s-memory-
transhuge.html>
What we need to do pseudo code:
if (`cat /sys/kernel/mm/redhat_transparent_hugepage/enabled` != 'never'); then
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
end
We need to add a check, and then add the 'echo never' to the python script.
