Thanks for the review and the comments, @joewitt and @ijokarumawak. I
understand. I simply added the description to the option in the parent
processor of HDFS.
I created a common additionalDetails.html in PutHDFS for now, but later it
would be useful if there is a common space which is refered from processors.---
