Being a newbie, can you point out where in the documentation it talks of waiting 2 minutes between starts of each node?
I ask this because I had looked at what was documented for clustering and even for backup and restore and did not feel I saw anything that mentioned this. Remember I also posted at how the restore did not seem to be working as expected (where I had num_tokens: 256 versus specifying tokens). Even if I tried to wait 2 minutes before restoring each node, it seemed I had to give all nodes all the sstable files after we stood up a new cluster. I figured it had to have been due to the token mismatch and giving each node all the sstables and cleaning them all up allowed each to get the data in its token range. So I just wanted to see where this concept is covered beyond the jira you just referenced that I can brush up on.
