> Add retries on the connection to the driver
> -------------------------------------------
>
> Key: SPARK-27989
> URL: https://issues.apache.org/jira/browse/SPARK-27989
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes, Spark Core
> Affects Versions: 2.4.3
> Reporter: Jose Luis Pedrosa
> Priority: Minor
>
> Due to Java caching of negative DNS resolution (failed requests are never retried).
> Any failure in the DNS when trying to connect to the driver, will make impossible a connection from that process.
> This happens specially in Kubernetes where network setup of pods can take some time,
>
