Hi there, I have some questions about the DFS functionality.
Case 1: Lets say there is a node which opens a file on the DFS to read. From my understanding, the open request will go to the namenode, which will tell it where the blocks of the file are. What if another node comes up and asks to delete that file. Of course this request will go to the namenode. How will the namenode respond in such a situation? Case 2: Whenever a node wants to delete a file, I think the request first lands with the namenode? What happens to the replicas of the blocks of that file, as soon as that file gets deleted? Thank you for all the help :) regards, -- Ahmad Humayun Research Assistant Computer Science Dpt., LUMS +92 321 4457315
