Actually, I am implementing kafka source for kafka0.8. When I ran the tests
for my implementation, I find the `ConsoleSink` cannot **continue** to process
data.
So I think if we provide `checkPointLocation` for the **sinks**, it can
continue to process data. If we do not provide this option, it is ok to start
from beginning. Not only the **other sinks**, I think all the sinks should
follow the pattern above.
