title: Oracle Number Type Column not converted from Bytes when it comes to Kafka
body: <p>I'm connecting <code>Oracle</code> to <code>Kafka</code> by using a <code>JDBC</code> connector. When data comes in from <code>Oracle</code>, it is converted correctly except for the <code>Oracle</code> Columns that are Numbers. For such columns, the data is not decoded.  The following is an example:</p>
  
  <blockquote>
    <p>{"ID":"\u0004{","TYPE":"\u0000Ù","MODE":"bytes":"\u0007"},"STAT_TEMP":{"string":"TESTING"}}</p>
  </blockquote>
  
  <p>I should mention that I'm also connecting the <code>Kafka</code> to spark such that I get the same output in the <code>spark</code>. </p>
  
  <p>I'm wondering what is the best way to convert the data? </p>
  
  <p>Whether to do it in <code>Kafka</code> or <code>spark</code>. If in Kafka, what is your suggestion in how to convert it?</p>
