title: Accessing files from other filesystems along with hdfs files in a hadoop mapreduce application
body: <p>I know that we can call a map-reduce job from a normal java application. Now the map-reduce jobs in my case has to deal with files on hdfs and also files on other filesystem. Is it possible in hadoop that we can access files from other file system while simultaneously using the files on hdfs. Is that possible ?</p>
  
  <p>So basically my intention is that I have one large file which I want to put it in HDFS for parallel computing and then compare the blocks of this file with some other files(which I do not want to put in HDFS coz they need to be accessed as full length file at once.</p>
