Sandy Ryza commented on YARN-2486:
----------------------------------
Unfortunately these methods were made public in 2.5, so we can't change their
signatures. We can, however, add versions with new names that return longs.
> FileSystem counters can overflow for large number of readOps, largeReadOps,
> writeOps

> Key: YARN-2486
> URL: https://issues.apache.org/jira/browse/YARN-2486
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.5.0, 2.4.1
> Reporter: Swapnil Daingade
> Priority: Minor
>
> 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.
