问题描述

我正在使用3个运行Ubuntu 16.04LTS的虚拟机虚拟机设置ambari集群.但是我收到以下警告:

I am setting up an ambari cluster with 3 virtualbox VMs running Ubuntu 16.04LTS. However I get the below warning:

The following hosts have Transparent Huge Pages (THP) enabled. 
THP should be disabled to avoid potential Hadoop performance issues.

如何在Ubuntu 16.04中禁用THP?

How can I disable THP in Ubuntu 16.04?

推荐答案

您是否尝试过以下命令:

Did you try this command:

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

?

或者，您可以安装 hugepages

sudo su
apt-get install hugepages
hugeadm --thp-never

如 @Anthony 所述，重新启动后效果不会持续.每次重新启动后，请使用特定于发行版的方法进行操作.

As mentioned by @Anthony, the effect would not persist after a reboot. Use your distribution-specific method to do that every time after reboot.
