If i have a file on hdfs and i have done some updation in it and i do know that hdfs internally make sure to update the replicated data as well. But i want to know how hdfs do it(i mean the workflow).
I have a csv file of 500MB, DFS block size 128MB and replication factor is 2. The file will get distributed into 4blocks and replicated to all the nodes.Now if i upate some values in file,what hdfs does to update all respective replicated data?
