Improve exception thrown by SpillRecord for bad spill index
-----------------------------------------------------------
Key: MAPREDUCE-2375
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2375
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
Fix For: 0.23.0
In trying to debug some issues on a cluster that was seeing shuffle fetch
failures, I found the IOException thrown by the SpillRecord constructor to be
insufficient. An improved exception would have more details about the file
path, offset, etc.
