title: aws kinesis data analytics application (flink) change property originally located at flink-conf.yaml
body: <p>As the runtime of my flink application I use managed flink by AWS (Kinesis Data Analytics Application)</p>
  
  <p>I added functionality (sink) for write processed events from kinesis queue in S3 in a parquet format.
  Locally everything works for me, but when I try to run the application in the cloud I get the following exception:</p>
  
  <pre><code>    "throwableInformation": [
          "com.esotericsoftware.kryo.KryoException: Error constructing instance of class: org.apache.avro.Schema$LockableArrayList",
          "Serialization trace:",
          "types (org.apache.avro.Schema$UnionSchema)",
          "schema (org.apache.avro.Schema$Field)",
          "fieldMap (org.apache.avro.Schema$RecordSchema)",
  </code></pre>
  
  <p>After finding a solution to the problem, I found that I need to change following property (checked this on a local cluster):</p>
  
  <p><em>classloader.resolve-order: child-first</em> -> <em>classloader.resolve-order: parent-first</em></p>
  
  <p>Is it possible to change this configuration when using AWS managed Fink (not EMR, Kinesis Data Analytics applications) in any way?</p>
