Eric Yang commented on HADOOP-5018:
-----------------------------------
Wouldn't it be better to decouple the pipeline logic from ServletCollector? It
may be better to have a interface between ServletCollector and Pipeline logic.
Hence, the pipline logic can be implemented as synchronized stages or
paralleled stages for different use cases. i.e duplication data filtering, or
real time monitoring alerts.
> Chukwa should support pipelined writers

> We ought to support chaining together writers; this will radically increase
> flexibility and make it practical to add new features without major surgery
> by putting them in pass-through or filter classes.
