> Key: SPARK-21642
> URL: https://issues.apache.org/jira/browse/SPARK-21642
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.0.0, 2.2.0
> Reporter: Aki Tanaka
> Assignee: Hideaki Tanaka
> Fix For: 2.3.0

> In current implementation, ip address of a driver host is set to DRIVER_HOST_ADDRESS [1]. This becomes a problem when we enable SSL using "spark.ssl.enabled", "spark.ssl.trustStore" and "spark.ssl.keyStore" properties. When we configure these properties, spark web ui is launched with SSL enabled and the HTTPS server is configured with the custom SSL certificate you configured in these properties.
> In this case, client gets javax.net.ssl.SSLPeerUnverifiedException exception when the client accesses the spark web ui because the client fails to verify the SSL certificate (Common Name of the SSL cert does not match with DRIVER_HOST_ADDRESS).
> To avoid the exception, we should use FQDN of the driver host for DRIVER_HOST_ADDRESS.
