Subject [jira] [Comment Edited] (YARN-6593) [API] Introduce Placement Constraint object
Date Wed, 02 Aug 2017 04:06:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16110248#comment-16110248

-------------------------------------------------------

The use-case is to be able to select containers based on key and values, say, I want to find
my containers with version=v1, and env = test, and foo !=bar and name=web1 or name = web2.
Yes, currently  it's a set of values not a single value, I misspoke. 
We can still make it work by searching the entire string as Arun said. But that's not explicit.
The AM, client, or even UI then needs to parse the string to extract the keys and values.


I was thinking this change will affect this jira's implementation also, hence continue commenting
here. If you think this anyways can be revisited. We can commit this first and work on it
in YARN-6594. It doesn't matter to me.

after patch is committed.
