title: How to process files with same name in Apache NiFi?
body: <p>I'm learning NiFi and I'm working on a flow where I get files using <code>GetFile</code> and then I do some process and then store them into HDFS using <code>PutHDFS</code> processor. The thing is, most probably I'll get files with the same name. For ex, I might get a file every 30 minutes and the file that is generated every 30 minutes will have the same name.</p>
  
  <p>Now when I put that file into HDFS, I get an "File with the same name already exists". How do I overcome this? Is there any way to change the file name on the run?</p>
