Nathan Roberts updated MAPREDUCE-5569:
--------------------------------------
Affects Version/s: 0.23.9
> 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: trunk, 2.1.0-beta, 1.3.0, 0.23.9
> 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.
