Hi all,
A failure node can rejoin a cluster.
On the node, all data in /var/lib/cassandra were deleted.
Is it normal?
I can reproduce it as below.
cluster:
- C* 2.2.7
- a cluster has node1, 2, 3
- node1 is a seed
- replication_factor: 3
how to:
1) stop C* process and delete all data in /var/lib/
To cassandra, the node where you deleted the files looks like a brand new
machine. It doesn’t automatically rebuild machines to prevent accidental
replacement. You need to tell it to build the “new” machines as a
replacement for the “old” machine with that IP by setting
-Dcassandra.replace_address_
