No. This is exactly what you are asking the node to do by setting false. The
goal of auto_bootstrap=true is to migrate data to the node automatically.
You can turn this method off if you have moved data their yourself out of
band (maybe rsync).

If you join a node with auto_bootstrap=false you had better be working at
quorum or higher to avoid stale/not found reads. You should then repair the
node right away to get all the missing data back on the node. This is not
suggested. It is best to leave auto_boostrap=true and let Cassandra handle
this on the front end.
