> Given a username as string of "0002", the username submitted to the parser
> for any STELLAR transformations is "2", and should be "0002". therefore, any
> further transforms do not occur.

> "sensorTopic": "metron_jira_topic",
> "parserConfig": {
> "grokPath": "/patterns/metron_jira_path",
> "patternLabel": "M_DELIMITED",
> "timestampField": "timestamp"
> },
> "fieldTransformations" : [
> {
> "transformation" : "STELLAR"

> { "username" : "TO_STRING(username)" }
> }
