[jira] [Commented] (SPARK-8425) Add blacklist mechanism for task
scheduling
[ https://issues.apache.org/jira/browse/SPARK-8425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15353277#comment-15353277 ]

-------------------------------------
Adding the design doc from SPARK-8426 here: https://docs.google.com/document/d/1R2CVKctUZG9xwD67jkRdhBR4sCgccPR2dhTYSRXFEmg/edit?usp=sharing
Also I want to point a change in behavior I am proposing in the design doc -- I think its best if there is *no timeout* for the blacklist *within one stage*. Once a task gets blacklisted for a particular stage, it will there forever. The timeout will only be for when executors and nodes get blacklisted across *all* stages. This greatly simplifies the implementation, and I dont' really think there is any significant downside.
OTOH, it *is* a behavior change from the old blacklisting.
