Nested field as Hbase row identifier

[#1]

I have a JSON document that I want to index into Hbase.

{
    "field1" : {
        "nestedfield" : "value1"
    }
    "field2" : "value2"
}

In this case I want `nestedfield` to be the one used as a row identifier field, but I can't figure out how to specify this to the `PutHBaseJson` processor. I have tried multiple ways :

- field1/nestedfiled

- field1['nestedfiled']

- field1.nestedfield

- $.filed1.nestedfiled

None of them are working, the processor is saying that "the Row ID was null".

Using `field2` for this purpose is working fwiw.
