> Key: MAPREDUCE-5862
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5862
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.3.0
> Reporter: bc Wong
> Assignee: bc Wong
> Attachments: 0001-Handle-records-larger-than-2x-split-size.patch,

>
> Suppose this split (100-200) is in the middle of a record (90-240):
> {noformat}
> 0 100 200 300
> |---- split ----|---- curr ----|---- split ----|
> <------- record ------->
> 90 240
> {noformat}
>
> Currently, the first split would read the entire record, up to offset 240,
> which is good. But the 2nd split has a bug in producing a phantom record of
> (200, 240).
