> While testing found below issue. For some of the task counters, we do not have consistent
values. This is not the case with every counter though.
> Consider the case of counter "org.apache.hadoop.mapreduce.FileSystemCounter:FILE_BYTES_WRITTEN".
> I found that its value for a flow I ran, was 936018 bytes. For the 3 apps associated
with this flow run, the values were 312006 bytes each (which equals to value for a flow run
i.e. 3 * 312006 = 936018). Drilling further down I found though that for one of the apps,
the 4 tasks(2 mappers and 2 reducers) had values as 155918 bytes each for the 2 reducers and
156003 bytes each for the 2 mappers.
> This means the value reported for the app should be (2 * 156003 + 2* 155918) or 623842
bytes but it is only 312006 bytes which indicates that only counter value of mappers is being
picked up.
