Summary: Report correct spill/output size for map in nativetask
Key: MAPREDUCE-6755
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6755
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: nativetask
Affects Versions: 2.6.0
Reporter: He Tianyi
Priority: Minor
Currently nativetask always report '-1' as size when calling methods in
{{MapOutputFile}}.
This is an obstacle for custom {{MapOutputFile}} implementations where size
matters (e.g. determine which disk to use).
The issue propose to estimate spill/output/index size in nativetask like java
implementation does.
