------------------------------------
Summary: Wrong CharType convertion in type_utils.py
Key: FLINK-12456
URL: https://issues.apache.org/jira/browse/FLINK-12456
Project: Flink
Issue Type: Bug
Reporter: Jingsong Lee
In types.py: define CharType as SQL CHAR, but SQL CHAR is a Java String instead
of Java Character.
In type_utils.py,
org.apache.flink.api.common.typeinfo.Types.CHAR map to DataTypes.CHAR, it is
wrong. Types.CHAR is Java Character.
I suggest that consider removing Char's support first.
