Subject [jira] [Commented] (YARN-3557) Support Intel Trusted Execution Technology(TXT) in YARN scheduler

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

Hi [~Naganarasimha],
{quote}constraints should be supported to be added from both RM and NM and partitions (existing
labels) should be allowed either by RM or NM{quote}
Agree with you that constraints should be supported to be added from both RM and RN. TRUSTED/UNTRUSTED
are also more like constraints of a node. BTW, it seems that constraints support is already
created(YARN-3409).

> 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.
