> Runtime type inference error when join three table for different column type
> -----------------------------------------------------------------------------
>
> Key: HIVE-18144
> URL: https://issues.apache.org/jira/browse/HIVE-18144
> Project: Hive
> Issue Type: Bug
> Components: Query Planning
> Affects Versions: 2.1.1, 2.2.0
> Reporter: Wang Haihua
> Assignee: Wang Haihua
> Attachments: HIVE-18144.1.patch, HIVE-18144.2.patch,
> HIVE-18144.3.patch

> Union operation with three or more table, which has different column types,
> may cause type inference error when Task execution.
> E.g, e.g. t1(with column int) union all t2(with column int) union all t3(with
> column bigint), finally should be {{bigint}},
> RowSchema of union t1 with t2, we call {{leftOp}}, should be int, then leftOp
> union t3 should finally be bigint.
> This mean RowSchema of leftOp would be {{bigint}} instead of {{int}}
> However we see in {{SemanticAnalyzer.java}}, leftOp RowSchema is finally
> {{int}} which was wrong:
> {code}
> (_col0: int|{t01-subquery1}diff_long_type,_col1:
> int|{t01-subquery1}id2,_col2: bigint|{t01-subquery1}id3)}}
> {code}
> Impacted code in SemanticAnalyzer.java:
> {code}
> if(!(leftOp instanceof UnionOperator)) {
> Operator oldChild = leftOp;
> leftOp = (Operator) leftOp.getParentOperators().get(0);
> leftOp.removeChildAndAdoptItsChildren(oldChild);
> }
> // make left a child of right
> List<Operator<? extends OperatorDesc>> child =
> new ArrayList<Operator<? extends OperatorDesc>>();
> child.add(leftOp);
> rightOp.setChildOperators(child);
> List<Operator<? extends OperatorDesc>> parent = leftOp
> .getParentOperators();
> parent.add(rightOp);
> UnionDesc uDesc = ((UnionOperator) leftOp).getConf();
> // Here we should set RowSchema of leftOp to unionoutRR's, or else the
> RowSchema of leftOp is wrong.
> // leftOp.setSchema(new RowSchema(unionoutRR.getColumnInfos()));
> uDesc.setNumInputs(uDesc.getNumInputs() + 1);
> return putOpInsertMap(leftOp, unionoutRR);
> {code}
> Operation for reproduceļ¼
