--------------------------------------
I'll number, but I want to move to RB anyway -- still waiting on the INFRA
ticket.
logging stacktrace: I'm thinking of it from the steady-state perspective. You
have a job happily running along. It times out to the broker periodically, or
spins when there's a network partition or whatever. The case you're describing
sounds like a case where you should turn debug on. Maybe we can add "Turn debug
on for more details" to the error message, or something. I'm just really
sensitive to filling the logs with meaningless junk in the "happy path", which
is what happens if you do ", e)". We had it that way in 0.6, and the logs are
really messy. I don't want to be in a situation where we're telling people to
ignore stack traces because it's not an error.
Logging: YARN does not handle rolling over STDOUT. Indeed, there does not seem
to be a good/easy way to do this on Linux. Some solutions require piping STDOUT
through a tool that does the rolling. I have not seen a way to do this easily.
I don't think M/R handles it either. The correct approach is to use a logging
system that rolls the logs properly.
Config: we need to open a "make config suck less" ticket, and get on it. It's
just a bit painful right now. It doesn't help that we (..or I..) keep renaming
config parameters on master either.
