Hey @Manoj690,
Thanks for reaching out to the Cloudera community.
You can execute a PUT request using the mentioned path "/connectors/<Connector_name>/config" to update the configuration for an existing connector. Also, pass a JSON object with the update parameter/s in the PUT request.
Example request:
PUT /connectors/<Connector_name>/config
Accept: application/json
{
"flush.size": "100",
"rotate.interval.ms": "1000"
}
Let me know if this helps.
