Eric Yang commented on CHUKWA-369:
----------------------------------
The list command check may be a scalability problem for the namenode with many
collectors/agents. When there are thousands of Agents issuing size check, this
will periodically spike the namenode. I think you will want to avoid this.
Jerome is more familiar with localWriter, and it seems quota feature is already
committed. Perhaps you could try localWriter instead of SeqFileWriter?

> 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
