Eric Yang commented on CHUKWA-369:
----------------------------------
Writer.add() throws exception if there is a problem. I think if add method is
called without exception, it means data is committed properly. If the data is
not on disk, the bug should be fixed inside the add method rather than changing
the return code because return code does not improve validation. If it fails,
throws WriterException is more proper.

> We like to say that Chukwa is a system for reliable log collection. It isn't,
> quite, since we don't handle collector crashes. Here's a proposed
> reliability mechanism.
