-----------------------------------
Summary: QueryRecord ignores field nullability and causes NPE with
null input value
Key: NIFI-5802
URL: https://issues.apache.org/jira/browse/NIFI-5802
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.2.0
Reporter: Koji Kawamura
Assignee: Koji Kawamura
WIth Avro schema, a field can be defined as nullable by a union type. For
example:
{code}
"type": [ "null", "boolean" ]
{code}
QueryRecord generates relational data types from the record schema. But it
currently doesn't utilize the nullable information. And it leads to a
NullPointerException when the incoming FlowFile has null values for the
nullable fields.
A simple 'select * from FLOWFILE' can fail.
This issue was reported to nifi user ML. See the message for detail.
