Weiwei Yang commented on YARN-7142: ----------------------------------- Hi [~gsaha]/[~leftnoteasy] Thanks for backing port this to branch-3.1. Not related to this task, I have a question about the format of placement policy in yaml file. It looks like it is more like an interpretation of how we specify placement constraints using Java API. I think we should be able to support a simple PC language, by specifying something like: {code} notin,node,foo {code} see more in [^Placement Constraint Expression Syntax Specification.pdf], YARN-7921. I know this is only used distributed shell as a demo, but I think if we find this more easier to write, maybe we can use such expression here too? Just want to know your opinion.
