Thanks [~kkaranasos], is this umbrella depending on YARN-3409 (that one seems
to be the umbrella to add node attributes)? I roughly went through the
discussions in YARN-3409 (what a long discussion :P) and it appears to so,
correct me if I am wrong. Thank you.

Thanks [~kkaranasos], is this umbrella depending on YARN-3409 (that one seems
to be the umbrella to add node attributes)? I ams asking because I did not find
any child tasks under this umbrella to manage node attributes and process
constraints with respect to the attributes.
One more thing, except simple operator {{IN}} or {{NOT_IN}}, I think there are
some more to be supported such as {{GT}} (greater than), {{GE}} (greater than
or equal to), {{LT}} (less than), {{LE}} (less than or equal to). For example,
{code}
{target: node-attribute:diskNum GT 5, scope host}
{code}
allocate to node where its diskNum > 5. This is very useful for long running
services.
