Strongly suspect that he has invalid unicode characters in his keys.
0.6 wasn't as good at validating those as 0.7.

Thanks for the pointer. I restarted entire cluster and started nodes at the
same time. However, I still see the issue. The view is not consistant. Am
running 0.7.5.
In general, if a node with bad ring view starts first, then I guess the
restart also doesnt help as it might be propagating its view

Hi All,
I want to use datacenter ShardStrategy in my cassandra setup
.Can someone please let me know what steps / configuration changes I need to
make.

Is there a more detailed document available on CF Histograms?

Hi,
I am trying to bring up a new node (with different IP) to replace a dead
node on cassandra 0.7.5. Rather than bootstrap, I am copying the SSTable
files to the new node(backed up files) as my data runs into several GB.
Although the node successfully joins the ring, some of the ring nodes sti

What version are you on ?
Check the nodetool ring from each node in your cluster to check they have the
same view.
Hope that helps.

Ah, I see the case you are talking about.
If the node will auto bootstrap on startup if when it joins the ring: it is not
already bootstrapped, auto bootstrap is enabled, and the node is not in it's
own seed list.
In the auto bootstrap process then finds the token it wants, but aborts the

Timeouts (hence errors) will register at the rpc timeout value.

I have a 4 node ring that was setup with tokens a,b,c,d using NTS and
2 nodes in each of 2 datacenters with a replication of DC1:1, DC2:1.
I was getting uneven replica placement so I did a drop keyspace,
followed by a nodetool move to DC1 having tokens (a,b) and DC2 having
tokens (a+1,b+1) , then
AFAIK Token suport is there for the hadoop integration and is not something you
should normally need to use.
It will be easier to use a KeyRange with a start_key if you have a consistent
key format, with the most significant discriminator first. e.g. /id
Then you can use a range start such as

Probably because unused sstables were deleted on start-up that were

Hi All,
I stop my cassandra node and restarted it,this start and stop
resulted in decrease in the space used by cassandra by 20%.
I am not sure what is happening?Can Anyone please shower some light on this
behaviour.
Thanks
