----------------------------------
Summary: Line records longer than 2x split size aren't handled
correctly
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
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).
We don't want to end up creating a phantom record of (200-240).
