body: <p>What kind of file formats can be read using PIG?</p>
  
  <p>How can I store them in different formats? Say we have CSV file and I want to store it as MXL file how this can be done? Whenever we use STORE command it makes directory and it stores file as part-m-00000 how can I change name of the file and overwrite directory?</p>
