title: Accessing information from a file dependent on another file in hadoop
body: <p>Hai i want to write a MapReduce program which takes two files as input ,( for eg : 
  file1 : Account Details
  file2 : Transaction Details) and take the account details from the file1 and access the corresponding account transaction details from file2. Here files are dependent if we want to access transaction details we need particular account details..Assuming that both files are in a single folder and that folder is passing as input to the map reduce program. </p>
