details: "In Apache Spark versions prior to 3.4.0, applications using spark-submit\
  \ can specify a 'proxy-user' to run as, limiting privileges. The application can\
  \ execute code with the privileges of the submitting user, however, by providing\
  \ malicious configuration-related classes on the classpath. This affects architectures\
  \ relying on proxy-user, for example those using Apache Livy to manage submitted\
  \ applications.\n \nUpdate to Apache Spark 3.4.0 or later, and ensure that \nspark.submit.proxyUser.allowCustomClasspathInClusterMode\
  \ is set to its \ndefault of \"false\", and is not overridden by submitted applications.\n\
  \n\n"
