[jira] [Commented] (SLIDER-726) Different instances of the same component should run on different nodes (anti-affinity)

["Steve Loughran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLIDER-726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14386502#comment-14386502 ] 

Steve Loughran commented on SLIDER-726:
---------------------------------------

SLIDER-799 has done a lot of work on re-requesting nodes after a failure; it can now configure a component type to wait minutes on each request for a new instance, before relaxing the placement policy from the previous node, and we do track failures better.

With that done, all that's in this JIRA is the SLIDER-84 anti-affinity need. I'm going to close this as a duplicate of that.

> To let component run on different will be very useful, for these reasons
> 1. many distributed services want to or should be run on different nodes
> 2. slider try to let yarn be a common resource OS
> If this feature is add, slider will be more popular
