----------------------------------
Summary: Undefined behavior in the conversion from
DataStream/DataSet to Table
Key: FLINK-11142
URL: https://issues.apache.org/jira/browse/FLINK-11142
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.7.0
Reporter: Yangze Guo
When we try to convert DataStream/DataSet to Table. There are two ways of
adding schema information, *ByName* or *ByPosition*.
This feature first proposed in [this
pr|https://github.com/apache/flink/pull/5132].
In *ByPosition* mode, the current code does not check if the number of fields
less than its in DataStream/DataSet. This may cause undefined behavior, e.g.
make a projection in *ByPosition* mode.
We can either fix it by adding some checking or regard this as a feature and
just improve the doc to clarify it. In my opinion, the latter way seems better.
[~twalthr] Could you take a look at it when you free?
