Swapnil Daingade updated HADOOP-11044:
--------------------------------------
Status: Patch Available (was: Open)
Based on the discussion on the JIRA decided to go with the approach suggested
by Gary.
2) Add new methods to return long types and switch the internal types to long
and simply cast the internal longs to ints when returned via the int methods.
Mark the int methods deprecated, then remove them after next release. This puts
overflow problem onto the int type methods.
> FileSystem counters can overflow for large number of readOps, largeReadOps,
> writeOps

> 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.
