Mehakmeet Singh commented on HADOOP-17018:
------------------------------------------
# I think 404 is representing an assertion got failed, here. I tried failing
some assertions and got 404, each time.
# Successful runs don't have any 404s. There is a 404 at the beginning of a
test and end of a test. I think that is due to setup and teardown as you said.
# I will add these counters alongside Network statistics. But, in this case, I
don't think a response(404) is the reason for failures, could be configurations
or even setup related too as you said.
This does become hard to reproduce, I'll look into that prefetch scenario and
see if I can find the reason for the failures.
