I'm just wondering -- what's wrong with manual specification of tokens?
I'm so glad I did it and have not had problems with balancing and all.

Hello,
Wondering how would one add Composite Keys rows using CLI. Supposing we
have CF defined below:
create column family ListTransactions
with comparator
If you can handle the load without the three machines, and you are still
meeting your redundancy requirements removing them may make your life easier.
Otherwise you have to consider that your cluster is made up of machines with
the worst parts from all of the nodes (i.e. lowest memory, slowest
If you are doing a straight one-to-one copy from one cluster to another try…
1) nodetool snapshot on each prod node for the system and application key
spaces.
2) rsync system and app key space snapshots
3) update the yaml files on the new cluster to have the correct initial_tokens.
This is not
Sounds like the schema has not fully migrated to the new node. It is applied to
the joining node one change at a time. A quick scan of the changes file does
not find anything fixed after 1.0.3
You can check schema versions in the CLI using the describe cluster command.
Check for errors in the
I see. Sure, that's a bit more complicated and you'd have to move tokens
after adding a machine.

Yep. Have written groovy script this friday to perform autobalancing :) I
am going to add it to my jenkins soon.

Sounds like you need a custom, manual solution.

Without knowing what the IOErrors are I would do the following:
nodetool scrub to fix any on disk errors, this will also take a snapshot you
can use for rollback.
nodetool repair to ensure data is consistent.
Hope that helps.

That sounds like to many sstables.
Out of interest were you using multi threaded compaction ? Just wondering about
this
