Eugene Koifman commented on HIVE-12521:
---------------------------------------
It maybe useful to rework the Exceptions in the API. There are 8 or 9
exceptions but most seem to confuse things by wrapping underlying exceptions
but not adding any more "context" info, e.g. StreamingIOError.
> Better javadoc for Hive streaming

>
> There are issues in HiveEndPoint and related interfaces that are not
> sufficiently documented.
> # There are no comments on thread safety even though the classes are not
> re-entrant.
> # The meanings of the different exceptions are not documented, even though
> the code returns different exceptions for different conditions and expects
> calls to re-act differently.
