Avro schema definitions

The parquet file format uses Avro schema for object definition. These Avro schemas are placed in the src/main/resources folder in both the projects. A typical Avro schema for address is as shown here:

{   "namespace": "example.avro",   "type": "record",   "name": "Contact",   "fields": [      {"name": "id", "type": "string"},      {"name": "customerId",  "type": "string"},      {"name": "street1", "type": "string"},      {"name": "street2", "type": "string"},      {"name": "city", "type": "string"},      {"name": "state", "type": "string"},      {"name": "country", "type": "string"},      {"name": "zipCode", "type": "string"}   ]}
