bc Wong created MAPREDUCE-5862: ---------------------------------- 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). -- This message was sent by Atlassian JIRA (v6.2#6252)
