Apache Spark reassigned SPARK-27272:
------------------------------------
Assignee: Apache Spark
> Enable blacklisting of node/executor on fetch failures by default
> -----------------------------------------------------------------
>
> Key: SPARK-27272
> URL: https://issues.apache.org/jira/browse/SPARK-27272
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: Ankur Gupta
> Assignee: Apache Spark
> Priority: Major
>
> SPARK-20898 added a new configuration to blacklist a node/executor on fetch
> failures. This config was deemed risky at the time and was disabled by default
> until more data is collected.
> This commit aims to enable that feature by default as we have seen couple of
> instances where that feature was found to be useful. The failures occur
> because of issues with node manager and external shuffle service on that node.
