Description

The org.apache.hadoop.fs.FileSystem.Statistics.StatisticsData class defines readOps, largeReadOps, writeOps as int. Also the The org.apache.hadoop.fs.FileSystem.Statistics class has methods like getReadOps(), getLargeReadOps() and getWriteOps() that return int. These int values can overflow if the exceed 2^31-1 showing negative values. It would be nice if these can be changed to long.
