Juntao Hu created FLINK-29648: --------------------------------- Summary: "LocalDateTime not supported" error when retrieving Java TypeInformation from PyFlink Key: FLINK-29648 URL: https://issues.apache.org/jira/browse/FLINK-29648 Project: Flink Issue Type: Bug Components: API / Python Affects Versions: 1.16.0 Reporter: Juntao Hu Fix For: 1.16.0
The following code raises "TypeError: The java type info: LocalDateTime is not supported in PyFlink currently.": {code:java} t_env.to_data_stream(t).key_by(...){code} However, this works: {code:java} t_env.to_data_stream(t).map(lambda r: r).key_by(...){code} Although we add Python coders for LocalTimeTypeInfo in 1.16, there's no corresponding typeinfo at Python side. So it works when a user immediately does processing after to_data_stream since date/time data has already been converted to Python object, but when key_by tries to retrieve typeinfo from Java TypeInformation, it fails. -- This message was sent by Atlassian Jira (v8.20.10#820010)
