nit: if we import some classes from org.apache.hadoop.fs.statistics, couldn't we import them in the same way? is there a specific reason for static importing this method?
I guess these would look better together, like:

import org.apache.hadoop.fs.statistics.IOStatisticsLogging;
import org.apache.hadoop.fs.statistics.IOStatisticsContext;
