-----------------------------------------
Summary: JsonTreeReader: schema inference gives wrong result
Key: NIFI-10957
URL: https://issues.apache.org/jira/browse/NIFI-10957
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.19.0, 1.16.3
Reporter: Jean-Pierre Milhau
I am using the JsonTreeReader with the schema access strategy set to Infer
schema.
For the following data in input:
{code:java}
{"alt": 12}
{"alt": null}{code}
the inferred schema gives field "alt" as a nullable INT, what is good.
But for the following data in input:
{code:java}
{"location": {"alt": 12}}
{"location": {"alt": null}}{code}
the inferred schema gives field "alt" (inside record "location") as a nullable
CHOICE(STRING, INT), what seems to me incorrect because there is no string
value for field "alt". I am expecting field "alt" as a nullable INT as when it
is on the root of the json document.
