Haohui Mai commented on HADOOP-11709:
-------------------------------------
I don't quite follow that why this is necessary as it is a simple exercise of
constant propagation from the compiler point of view?
> Time.NANOSECONDS_PER_MILLISECOND - use class level final constant instead of
> method variable

> NANOSECONDS_PER_MILLISECOND constant can be moved to class level instead of
> creating it in each method call.
> {code}
> org.apache.hadoop.util.Time.java
> public static long monotonicNow() {
> final long NANOSECONDS_PER_MILLISECOND = 1000000;
> return System.nanoTime() / NANOSECONDS_PER_MILLISECOND;
