oh interesting, it uses IP for hinted hand off? which brings up
another interesting question, if the node that went down never came up
again, how long will the hinted handoff keep going? Indefinitely?
On the first topic of backup/restore, you suggested copying the
sstable files over from the 2
So, is there anyway to recover if you can't guarantee the same IP address?
Since we are running on EC2 (as I'm sure are others on the list), and there
is no way to make this guarantee.
Is this sort of recoverability on the roadmap anywhere?
Thanks,

Currently, no. Feel free to open a ticket. It would be fairly easy
to make the decommission code in trunk handle this.

Hello Everyone,
Is there a recommended backup/restore procedure to be able to recover a
failed node?
How does Cassandra keep track of a node's identity?
Should a replacement node keep the same IP address/DNS name as the original
node?
Does a node still receive data while a nodeprobe snapshot

Until tickets 193 and 520 are done, the easiest thing is to copy all
the sstables from the other nodes that have
Hey Jonathan, why should a replacement node keep the same IP
address/DNS name as the original node? Wouldn't having the same token
as the node that went down be sufficient (provided that you did the
steps above of copying the data from the 2 neighboring nodes)?
On Wed, Nov 18, 2009 at 10:30 AM,
Tokens can change, so IP is used for node identification, e.g. for
hinted handoff.

Hello Jonathan,
Is the system table information contained in the system/Location* files?
How do I know which nodes hold the replicated copies when using ordered
preserving partitioning? Are replicas always stored in neighboring nodes?
Are the left (before) and right (after) nodes you mentioned
I'm sorry if this was covered before, but if you lose a node and
cannot bring it (or a replacement) back with the same IP address or
DNS name, is your only option to restart the entire cluster? E.g. if
I have nodes 1, 2, and 3 with replication factor 3, and then I lose
node 3, is it possible to
No, bootstrap is currently only for adding new nodes, not replacing dead ones.
