Hi I have a scenario where, while a map/reduce is working on a file, the input file may get deleted and copied with a new version of the file. All my files are compressed and hence each file is worked on by a single node. I tried simulating the scenario of deleting the file before mapreduce was over, and map/reduce went ahead without complaining. Can I assume this will be the case always.
Many thanks in adv Sandhya
