Description

I see the following test failures when updating avro dependency from 1.5.3 to 1.7.1:

• MySQLLobAvroImportTest
• OracleLobAvroImportTest

The reason is because byte[] fails to be mapped to avro bytes type (see below the isBytes() method of GenericData in avro 1.7.1).

/** Called by the default implementation of {@link #instanceOf}.*/
protected boolean isBytes(Object datum) {
  return datum instanceof ByteBuffer;
}

The fix is to wrap byte[] as ByteBuffer so that avro GenericData can map it to bytes type.
