I googled and found some article saying THP is not for Hadoop workload like below.</P><P><A href="https://community.cloudera.com/t5/Community-Articles/OS-Configurations-for-Better-Hadoop-Performance/ta-p/247300" target="_blank">https://community.cloudera.com/t5/Community-Articles/OS-Configurations-for-Better-Hadoop-Performance/ta-p/247300</A></P><P>&nbsp;</P><P>I think you pointed out that our NodeManager went wrong due to the some workload happened and our node running NodeManager couldn't deal with it. Is my understanding correct?</P><P>&nbsp;</P><P>I will configure this in our test environment first. Not knowing how this situation happened, I need some time to verify. If any progress or additional query, I will post again.</P><P>&nbsp;</P><P>Thank you very much again.</P><P>&nbsp;</P><P>Best regards,</P><P>Yosuke</P> Tue, 11 May 2021 20:48:22 GMT yosuke 2021-05-11T20:48:22Z
