> While I tried to implement SSL for the master UI, we were getting the below

> org.spark_project.jetty.util.ssl.SslContextFactory. (Use

> org.spark_project.jetty.util.ssl.SslContextFactory$Client instead)
> at
> org.spark_project.jetty.util.ssl.SslContextFactory.newSniX509ExtendedKeyManager(SslContextFactory.java:1283)

> not having any issues.
> Please suggest how we can mitigate this issue in the latest version of the
> spark-core_2.11-2.4.8
