    What? I'm talking about the shuffle secret the executor container needs when it initially
registers with the shuffle service: https://github.com/apache/spark/blob/6cd98c1878a9c5c6475ed5974643021ab27862a7/yarn/src/main/scala/org/apache/spark/deploy/yarn/ExecutorRunnable.scala#L116.
The whole motivation for adding that in the first place is for app-level authentication during
the registration.
