@ijokarumawak thanks! The changes look good. I ran build with contrib-check
and unit test helps. +1 merged to master.
> AvroTypeUtil throws Exception before trying every possible type
> ---------------------------------------------------------------
>
> Key: NIFI-3919
> URL: https://issues.apache.org/jira/browse/NIFI-3919
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.2.0
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
> Fix For: 1.3.0
>
>
> With a field schema having mixed types, for example, "[null, int, string]",
> AvroTypeUtil tries to coerce type conversion so that the input raw object can
> fit with one of possible data type defined in the union.
> If an input string "bar" is passed, we expect it's mapped as "string" data
> type. However, the "bar" is parsed as integer first, and a
> NumberFormatException is thrown but not caught, before converting it to
> "string".
> We surround type conversion with try/catch when AvroTypeUtil tries to find a
> right type within an union field so that it can check every possible type.
