----------------------------------
Summary: Support map type in flink-json
Key: FLINK-14546
URL: https://issues.apache.org/jira/browse/FLINK-14546
Project: Flink
Issue Type: Bug
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Affects Versions: 1.9.1, 1.8.2
Reporter: Benchao Li
Currently in flink-json, we don't treat map type as a special type, which
results that the type of map is deduced from fastjson.
For example, when we set `map<varchar, int>` in SQL DDL，and get a value large
than int_max, which will result in `Long` from fastjson, and will cause a
runtime error.
