Thomas Graves updated SPARK-24413:
----------------------------------
Summary: Executor Blacklisting shouldn't immediately fail the application
if dynamic allocation is enabled and no active executors (was: Executor
Blacklisting shouldn't immediately fail the application if dynamic allocation
is enabled and it doesn't have any other active executors )

> allocation is enabled and no active executors

> Key: SPARK-24413
> URL: https://issues.apache.org/jira/browse/SPARK-24413
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler
> Affects Versions: 2.3.0
> Reporter: Thomas Graves
> Priority: Major
>
> Currently with executor blacklisting enabled, dynamic allocation on, and you
> only have 1 active executor (spark.blacklist.killBlacklistedExecutors setting
> doesn't matter in this case, can be on or off), if you have a task fail that
> results in the 1 executor you have getting blacklisted, then your entire
> application will fail. The error you get is something like:
> Aborting TaskSet 0.0 because task 9 (partition 9)
> cannot run anywhere due to node and executor blacklist.
> This is very undesirable behavior because you may have a huge job but one
> task is the long tail and if it happens to hit a bad node that would
> blacklist it, the entire job fail.
> Ideally since dynamic allocation is on, the schedule should not immediately
> fail but it should let dynamic allocation try to get more executors.
