Haohui Mai commented on HADOOP-9670:
------------------------------------
An NfsTime instance has to be serialized into a XDR tuple (i.e., (seconds,
nanoseconds)) when it crosses the network wire. It seems to me that it is more
efficient to keep both values in the memory rather than performing a division
and a modularization during serialization.
> Use a long to replace NfsTime
