@hmcl I'd be happy to add comments explaining the propagation. Calling
`close()` isn't enough. When the Kafka exception is thrown, the thread
interrupt state is cleared (same behavior as the Java exception). If we just
call `close()`, the executor thread keeps running because it's no longer
interrupted (though it would probably crash on the next call to nextTuple since
the consumer was closed). We have to either throw a wrapped
InterruptedException, or reinterrupt the thread.
