Unfortunately, the checkpoint image that I have has the deletes recorded. I cannot use it. I do have an image that is 15 days old, which I am currently running.
I looked at the my logs and I have the filename, block allocated and generation stamp. Can you explain to me the importance of the generation stamp here? Since my hdfs cluster is operational with the old image and I am writing new data to it, the generation stamp must have been incremented beyond what it was 15 days ago. If I try to restore a block that we written, lets say, 13 days ago, there can be generation stamp collision. So, if I stop my cluster and make the new entries with generation stamp increments after what is currently in the namenode, will it be ok? Is the generation stamp stored somewhere in the datanode or the block stored in the datanode? Thanks for the clarifications.
