--------------------------------------
Summary: 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: 2.4.1
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.
