Holden Karau commented on SPARK-20624:
--------------------------------------

[~hyukjin.kwon] that doesn't seem comparable, the history service is an 
existing feature with a lot of use and that involved 18 distinct 
sub-components. If folks wanted an SPIP for it there was plenty of time from 
when I shared the updated design doc, PR, and e-mailed the dev@ list.

> While we've done some good work with better handling when Spark is choosing 
> to decommission nodes (SPARK-7955), it might make sense in environments where 
> we get preempted without our own choice (e.g. YARN over-commit, EC2 spot 
> instances, GCE Preemptiable instances, etc.) to do something for the data on 
> the node (or at least not schedule any new tasks).
