> In many places in Wake and REEF, we do not make sure that executor services and related
threads are being shut down properly. Instead, we assume that all threads that are still running
after REEF job finishes will be shut down when we terminate the JVM. This is not acceptable
in REEF Environment setting when REEF job has to run alongside with other applications, e.g.
Spark. Therefore, we have to implement proper shutdown procedures for all thread pools maintained
by Wake and REEF.
