Thx.#1 don't understand the "edit logs" remark.
well, that's something you need to work on as its the key to keeping your cluster working. The edit log is the journal of changes made to a namenode, which gets streamed to HDD and your secondary Namenode. After a NN restart, it has to replay all changes since the last checkpoint to get its directory structure up to date. Lose the edit log and you may as well reformat the disks.
