             Summary: Time.NANOSECONDS_PER_MILLISECOND - use class level final 
constant instead of method variable 
                 Key: HDFS-7919
                 URL: https://issues.apache.org/jira/browse/HDFS-7919
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Ajith S
            Assignee: Ajith S
            Priority: Trivial


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;
  }
{code}
