> Cleanup some non-compile time type checking and exception handling

> Key: SPARK-27731
> URL: https://issues.apache.org/jira/browse/SPARK-27731

> Components: Spark Core
> Affects Versions: 2.3.3
> Reporter: David C Navas
> Priority: Major
> Fix For: 3.0.0
>
>
> 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.
> Note that we also see an opportunity to simplify the KVStore implementation
> tests as the verification of the KVStore APIs should be independent of the
> implementation and the tests should probably be written once and then run
> against both implementations. However, we decided not to attempt that at
> this time.
