> This code:
> {code}
> private[spark] object RDDInfo {
>   private val callsiteLongForm = SparkEnv.get.conf.get(EVENT_LOG_CALLSITE_LONG_FORM)
> {code}
> Has two problems:
> - it keeps that value across different SparkEnv instances. So e.g. if you have two tests that rely on different values for that config, one of them will break.
> - it assumes tests always initialize a SparkEnv. e.g. if you run "core/testOnly *.AppStatusListenerSuite", it will fail because {{SparkEnv.get}} returns null.
