------------------------------------------
Summary: variable typo in HiveOpConverter line 714
Key: HIVE-10582
URL: https://issues.apache.org/jira/browse/HIVE-10582
Project: Hive
Issue Type: Bug
Components: Logical Optimizer
Reporter: Alexander Pivovarov
Assignee: Alexander Pivovarov
Priority: Minor
HiveOpConverter lines 703-717
{code}
int kindex = exprBack == null ? -1 : ExprNodeDescUtils.indexOf(exprBack,
reduceKeysBack);
if (kindex >= 0) {
ColumnInfo newColInfo = new ColumnInfo(colInfo);
newColInfo.setInternalName(Utilities.ReduceField.KEY + ".reducesinkkey"
+ kindex);
newColInfo.setAlias(outputColName);
newColInfo.setTabAlias(colInfo.getTabAlias());
outputColumns.add(newColInfo);
index[i] = kindex;
continue;
}
int vindex = exprBack == null ? -1 : ExprNodeDescUtils.indexOf(exprBack,
reduceValuesBack);
if (kindex >= 0) { // looks like it should be vindex instead of kindex
index[i] = -vindex - 1;
continue;
}
{code}
Most probably the second "if (kindex >= 0)" (line 714) should be replaces with
"if (vindex >= 0)"
