Yep, the hinted handoff in 1.0.8 is abysmal at best. What is your
replication facter, i have had huge hints pile up, where i had to drop the
entire coloumn family and then run a repair. Either that or you can use the
JMX HintedHandoffManager and delete hints per endpoint. Also it maybe
worthwhile t
Try the show keyspaces command and look for "Options" under each keyspace.

I could you perhaps check your ntp?

Since the older node is not available i would ask you to assassinate the
old node and then get the node new node to bootstrap.

And the token value as suggested is tokenvalueoddeadnode-1 ?

Are you replacing the node with the same token and the same IP?

I have seen the conflicts with sudo error but that was with 3.X rpm on the
amazon ami, i was how ever able to install it from the tar ball. As Nick
has pointed out, the versions of OS and Opscenter will help in looking at
this.

Francisco,
the sstables with *-ib-* is something that was from a previous version of
c*. The *-ib-* naming convention started at c* 1.2.1 but 1.2.10 onwards im
sure it has the *-ic-* convention. You could try running a nodetool
sstableupgrade which should ideally upgrade the sstables with the *-ib
You should refer to this

Looks like the error is being populated from the hintedhandoff, what is the
size of your hints cf?

Christian,
I have been planning to migrate my cluster from random to murmur3 in a
similar manner. I intend to use pycassa to read and then write to the newer
cluster. My only concern would be ensuring the consistency of already
migrated data as the cluster ( with random ) would be constantly servi

So basically when you run a repair you are essentially telling your cluster
to run a validation compaction, which generates a merkle tree on all the
nodes. These trees are used to identify the inconsistencies. So there is
quite a bit of streaming which you see as your network traffic.

You should look at this - https://github.com/amorton/cassback i dont
believe its setup to use 1.2.10 and above but i believe is just small
tweeks to get it running.

Tom,
You should check the size of the hints column family to determine how much
are present. The hints are a super column family and its keys are
destination tokens. You could look at it if you would like.
Hints send and timedouts are logged, you should be seeing something like
Timed out replayi
Tom,
Here is the definition
List all the endpoints that this node has hints for, and count the number
of hints for each such endpoint.
Returns:map of endpoint -> hint count
I would suggest looking at at the gossipinfo to validate if there are any
nodes which have that token value. If there is (
Oleg,
The system keyspace is not replicated it is local to the node. You should
check your logs to see if there are Timeouts from streaming hints, i
believe the default value to stream hints it 10 seconds. When i ran into
this problem i truncated hints to clear out the space and then ran a repair
