Change subject: IMPALA-8718: Fixed AnalysisException in inline view with outer join complex type column ...................................................................... IMPALA-8718: Fixed AnalysisException in inline view with outer join complex type column For Inline view with left outer join, in order to make right side exprs nullable, it makes a wrapper for the expr that return non-null when all its contained slotref is null. The wrap is TupleIsNullPredicate. Complex type does not need the wrapper for its value cannot both be null and non-null. But during its checking whether the wrapper needed, because of code limitation, AnalysisException is thrown. This fix overcomes the limitation by avoiding to use unsupported IsNullPredicate for complex type. It should be a safe change for: 1. Other data types such as int return false after a call to backend to check isNotNull(nullvalue). 2.Left outer join with complex type works fine for the queries without inline view. Join code can handle complex type correctly without the wrapper. Tests: Added ee tests to test left outer joins. Manual tests.
