title: How to access aws public dataset on S3?
body: <p>I am trying to load public data using pig from s3 using this url
  s3://datasets.elasticmapreduce/ngrams/books/20090715/eng-us-all/4gram/data</p>
  
  <p>LOAD 's3n://datasets.elasticmapreduce/ngrams/books/20090715/eng-us-all/4gram/data'</p>
  
  <p>but it is asking for access and secret key. Should I move this data to one of my buckets? or am I missing something</p>
