             Summary: Cleanup some odd-looking typing choices and exception handling
                 Key: SPARK-27731
                 URL: https://issues.apache.org/jira/browse/SPARK-27731
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Core
    Affects Versions: 2.3.3
            Reporter: David C Navas


Previous checkins cleaned up some of the odd exception propagation choices (Throwables.propagate is deprecated), there's a little more work on that here.  Additionally, the InMemory's InstanceList wasn't previously generically typed, which made some of the code excessively cautious.  I added the generic typing and removed the sprinkling of Precondition checks which seems to have been designed to work around not having proper compile-time type checking.  Also, it turned out to be unnecessary to track the class in the KVStoreView, which allows for the easy creation of an EMPTY_VIEW singleton.
