Review Comment:
I am not sure this implements the contract correctly.

/**
* Fetch elements into the blocking queue for the given splits. The
fetch call could be blocking
* but it should get unblocked when {@link #wakeUp()} is invoked. In
that case, the
* implementation may either decide to return without throwing an
exception, or it can just
* throw an interrupted exception. In either case, this method should be
reentrant, meaning that
* the next fetch call should just resume from where the last fetch call
was waken up or
* interrupted. It is up to the implementer to either read all the
records of the split or to
* stop reading them at some point (for example when a given threshold
is exceeded). In that
* later case, when fetch is called again, the reading should restart at
the record where it
* left off based on the {@code SplitState}.
*
* @return the Ids of the finished splits.
* @throws IOException when encountered IO errors, such as
deserialization failures.
