title: How do I retrieve pdf files stored in Hadoop HDFS from a webapp
body: <p>I am currently building a search engine for pdfs. I am using elastic search to ingest the the pdf data. As it has been advised by most people not to store binary files in elastic, it was suggested I store the files in Hadoop HDFS. However, how do I retrieve the the actual files stored HDFS from my webapp. Is there an API? Or simply adding a link to the pdf should retrieve it</p>
