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.
