> Project: Apache NiFi

>
> PutParquet (NiFi 1.7.1), will fail to write parquet if incoming records
> contain arrays with null elements:
> Schema snippet example:
> { "name": "myfield", "type" : ["null", \\{ "type" :
> "array", "items" : ["null","string"], "default": null }
> ], "default": null
> },
>
> And a corresponding data example:
> "myfield" : [ null, "value1" ],
> "myfield" : [ null, "value2" ],
> "myfield" : [ "value3", null, "value4" ],
>
> Avro does not seem to have a problem with this, but Put parquet fails with
> the following error: "Array contains a null element at X".
>
> There is a parquet config to allow this:
> parquet.avro.write-old-list-structure=false
>
> If the processor would have a box for toggling this value, or a text box to
> pass configs in general would be great!
