Subject [jira] [Commented] (YARN-3557) Support Intel Trusted Execution Technology(TXT) in YARN scheduler
Date Wed, 06 May 2015 11:01:08 GMT

    [ https://issues.apache.org/jira/browse/YARN-3557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14530339#comment-14530339

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.
