Eric Yang commented on CHUKWA-369:
----------------------------------
What is the algorithm used to identify the written bytes from chunk 2 from
server a as oppose to chunk 2 from server b if the data are stacked together?
There doesn't seem to be an easy way to identify if one of the chunk is missing.
Our deployment has collector mapped to exact number of datanode deployed.
100kb/sec from 25000 machines easily met the 2GB/sec data, Chukwa is designed
to process data in parallel with stateless transport. We need to ensure that
this solution does not impact parallelism.

> 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.
