Dian Fu commented on YARN-3557:
-------------------------------

Hi [~leftnoteasy],
I have reconsidered the support of script based node label configuration at RM 
side and think this support is meaningful. I agree that users can write a 
script and periodically executes the script to update the labels via REST APIs. 
But this requires users to execute the script with admin user. Moreover, I 
think this requirement is common and implementing this at RM side will ease the 
use. As NM side already has such support, an implementation at RM side will not 
require too many efforts.

> Intel TXT defines platform-level enhancements that provide the building 
> blocks for creating trusted platforms. A TXT aware YARN scheduler can 
> schedule security sensitive jobs on TXT enabled nodes only. YARN-2492 
> provides the capacity to restrict YARN applications to run only on cluster 
> nodes that have a specified node label. This is a good mechanism that be 
> utilized for TXT aware YARN scheduler.
