   @tgravescs  I am the author of Uber RSS. In terms of your question "I'm not 
familiar with the details of Uber RSS, can it just fake up a remote shuffle 
port and ignore what is sent? have you requested their version to support 
dynamic allocation?"... Uber RSS could support dynamic allocation on Kubernetes 
by some work around, e.g enabling shuffle tracking feature and set shuffle 
timeout to be zero. But it is a hack. The code change here will make that hack 
unnecessary.
   
   In terms of adding a config like "spark.shuffle.registration.enabled", any 
concern?
