--------------------------------
Assignee: Benchao Li
> 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: 1.8.2, 1.9.1
> Reporter: Benchao Li
> Assignee: Benchao Li
> Priority: Major
>
> 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.
