Nathan Roberts created MAPREDUCE-5569:
-----------------------------------------
Summary: FloatSplitter is not generating correct splits
Key: MAPREDUCE-5569
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5569
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.1.0-beta, trunk, 1.3.0
Reporter: Nathan Roberts
Assignee: Nathan Roberts
The closing split is not calculated correctly:
{code}
// Catch any overage and create the closed interval for the last split.
if (curLower <= maxVal || splits.size() == 1) {
splits.add(new DataDrivenDBInputFormat.DataDrivenDBInputSplit(
- lowClausePrefix + Double.toString(curUpper),
+ lowClausePrefix + Double.toString(curLower),
colName + " <= " + Double.toString(maxVal)));
}
{code}
For the case of min=5.0, max=7.0, 2 splits, the current code returns splits of
(column1 >=5.0, column1 <6.0), (column1 >=7.0, column1 <=7.0). The second split
is obviously not correct.
