Subject [jira] [Commented] (HADOOP-11044) FileSystem counters can overflow for large number of readOps, largeReadOps, writeOps

Swapnil Daingade commented on HADOOP-11044:
-------------------------------------------

Thanks Gary and Sandy. I'll update the bug if we find more places where counters are int types
and it would help if they are changed to longs.

> 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.
