Naganarasimha G R commented on YARN-3557:

Thats an interesting point here .  {{lables GPU, FPGA, LINUX, WINDOWS,}} these 
are more like constraints of a node for which a new jira is coming up and so 
may be once it comes in we need to support in such a way that constraints 
should be supported to be added from both  RM and NM and partitions (existing 
labels) should be allowed either by RM or NM ... thoughts ?

>         Attachments: Support TXT in YARN high level design doc.pdf
> 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.
