-----------------------------
Summary: Flink Table ApI not working with nested Json schema
starting From 1.6.x
Key: FLINK-13603
URL: https://issues.apache.org/jira/browse/FLINK-13603
Project: Flink
Issue Type: Bug
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
SQL / API
Affects Versions: 1.8.1, 1.7.2, 1.6.4
Reporter: Yu Du
Attachments: FlinkTableBugCode, jsonSchema.json, jsonSchema2.json
starting from Flink 1.6.2 , some schema not working when have nested object .
issue like : Caused by: org.apache.calcite.sql.validate.SqlValidatorException:
Column 'data.interaction.action_type' not found in table
Even we can see that column from Table Schema .
And the same schema and query working on 1.5.2 , but not working for 1.6.x ,
1.7.x and 1.8.x
I tried to dive into the bug, and found the root cause is calcite library
doesn't mapping the column name with the correct Row type .
I checked Flink 1.6 using the same version of Calcite as Flink 1.5 . Not sure
if Calcite is the root cause of this issue .
Attached with the code sample and two issue json schemas . both examples give
column not found exception .
