-----------------------------------------

             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.
