This suggests that yum is not flushing output, possibly because
it doesn't think it's stdio is on a tty.

1. Were you running yum update locally on the console, or
remotely via a network connection of some kind, e.g. ssh?
If you do it as a direct command to ssh (ssh myhost yum update)
you might get those symptoms, unless you also give -t to ssh:
ssh -t myhost yum update

2. If you were on the console, were you piping the output of
yum through something else like tee? e.g.
yum update | tee mylogfile
If so, you might again get the same symptoms. If you want to
capture the output of the session, use the script command:

# script mylogfile
Script started, file is mylogfile
# yum update
# exit
Script done, file is mylogfile
# 

If neither of the above is applicable, please explain exactly what
you did, step by step, including what you might consider insignificant.

Cheers
Tony
