Chris Nauroth commented on HADOOP-10612:
----------------------------------------
Hi, Brandon. The change looks good. Two questions:
# Is changing this config property name backwards-incompatible with existing
configs that are already deployed?
# Do you think it's worthwhile to switch to {{Time#monotonicNow}} so that this
isn't subject to system clock bugs? (i.e. Someone resets the clock to a time
in the past, and then updates don't happen for a long time.)
