Description

NiFi has a ValidateXml processor to validate incoming XML files against a schema. It would be good to have one to validate JSON files as well.

For example, an input JSON of:

{
name: "Test",
timestamp: 1463499695,
tags:

{ "host": "Test_1", "ip" : "1.1.1.1" }

,
fields:

{ "cpu": 10.2, "load": 15.6 }

}

Could be validated successfully against the following "schema":

{
"type": "object",
"required": ["name", "tags", "timestamp", "fields"],
"properties": {
"name":

{"type": "string"}

,
"timestamp":

{"type": "integer"}

,
"tags": {"type": "object", "items": {"type": "string"}},
"fields":

{ "type": "object"}

}
}

There is at least one ASF-friendly library that could be used for implementation: https://github.com/everit-org/json-schema
