Subject [jira] [Created] (SPARK-22294) Reset spark.driver.bindAddress when starting a Checkpoint

-----------------------------------------

             Summary: Reset spark.driver.bindAddress when starting a Checkpoint
                 Key: SPARK-22294
                 URL: https://issues.apache.org/jira/browse/SPARK-22294
             Project: Spark
          Issue Type: Improvement
          Components: Deploy, Spark Core
    Affects Versions: 2.2.0, 2.1.0
            Reporter: Santiago Saavedra


On SPARK-4563 support for binding the driver to a different address than the spark.driver.host
was provided so that the driver could be running under a differently-routed network. However,
when the driver fails, the Checkpoint restoring function expects that the {{spark.driver.bindAddress}}
remains the same even if the {{spark.driver.host}} variable may change. That limits the capabilities
of recovery under several cluster configurations, and we propose that {{spark.driver.bindAddress}}
should have the same replacement behaviour as {{spark.driver.host}}.
