Can't speak for the author's use case, but we needed this because we had a multi-home networking inside our yarn cluster, infiniband for internal and ethernet for external. I haven't been able to track how/why, but apparently the default behavior of executor bind address changed somewhere along the line between spark 2 and spark 3. Spark 2 used to always bind to 0.0.0.0, Spark 3 would first find it's own ip address basically by "pinging" it's own hostname and bind to whatever that returned. In our case that was an internal ip, hence client mode stopped working when we transitioned from Spark 2 to Spark 3 as driver was no longer able to reach executors. -- This is an automated message from the Apache Git Service.
