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

Hi [~sunilg],
Thanks for your comments. 
{quote}Apart from CLI and REST, do u mean like exposing these configuration for a specific
user (i assume this user will have some security approval in the cluster) so that this user
can make the config via REST or api's.{quote}
Exposing these configuration for a specific user can be one option. But this will require
users to start a job which updates the labels periodically and is complicated for users. If
we can provide the similar method to YARN-2495 at RM side, user will just need to provide
a script(which takes node hostname/ip as input and output the node labels).

> 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.
