In Park created NIFI-9033:
-----------------------------
Summary: Define Validators and Default Values for
NifiStatelessConnectors
Key: NIFI-9033
URL: https://issues.apache.org/jira/browse/NIFI-9033
Project: Apache NiFi
Issue Type: Bug
Reporter: In Park
Nifi Stateless Kafka Connectors' dataflow name config ("name") is colliding
with Kafka Connector's base "name" config:
[https://github.com/apache/nifi/blob/6df07df3b2d2dbabeb279ac749ed45c37efd5d01/nifi-external/nifi-kafka-connect/nifi-kafka-connector/src/main/java/org/apache/nifi/kafka/connect/StatelessKafkaConnectorUtil.java#L99]
Kafka Connector base "name" config has a validator while the NifiConnector's
"name" config doesn't, and this NifiConnector's validator (which is null) is
overriding the Kafka Connector's "name" validator, therefore config validation
gives a false positive.
The DATAFLOW_NAME config definition should be changed to something like the
following which includes a valid default value along with a correct validator.
{code:java}
configDef.define(DATAFLOW_NAME, ConfigDef.Type.STRING,
ConfigDef.NO_DEFAULT_VALUE, nonEmptyStringWithoutControlChars(),
ConfigDef.Importance.HIGH, "The name of the dataflow.");{code}
