You should iterate through them, get 200 then go get the next 200 and so on.
Also if checking a bounding box to another.. perhaps try sorting them so you
could start looking at both ends, perhaps make the iteration smaller until
match somehow?

Hi,
We are trying to implement Cassandra to replace one of our biggest SQL tables,
and so far we got it working.
However, for testing I'm using Cassandra 0.6.2, Java and Pelops. (Pelops not
that important for my question) and need suggestions on how to solve a problem

Needing to manually copy the jars to all of the nodes would mean that you
aren't applying the Pig 'register ;' command properly.

Hi,
We are searching at least 3 more developers in the fields of search &
automatic content/site extraction, crawling, duplicate content, news/spam
detection.
We do content fetching and aggregation (news,message boards, blogs, ...) for
market research institutes, media analytics companies, etc...
If you read the stack traces you pasted, the node in question ran out
of diskspace. When you have < 25% space free this is not surprising.
But fundamentally you are missing something important from your story
here. Disk space doesn't just increase spontaneously with "absolutely
no activity."

HH would handle it if it were a FD false positive, but if a node
actually does go down then it can miss writes before HH kicks in.

Guys,
Correct me if I am wrong. The whole problem is because a node missed an
update when it was down. Shouldn’t HintedHandoff take care of this case?

I have absolutely no idea what is causing the rejections, they appear to be
totally random, on all 3 hosts of my cluster. I cleared all iptables states,
and since they all sit on the same switch I don't think it has to do with
the underlying network. Is there a connection limit on Cassandra nodes?
Actually, tombstones are read repaired too -- as long as they are not
expired. But nodetool repair is much less error-prone than relying on
RR and your memory of what deletes you issued.
Either way, you'd need to increase GCGraceSeconds first to make the
tombstones un-expired first.

(a) if you're using token queries and you're not hadoop, you're doing it wrong
(b) they are expected to be of the form generated by
TokenFactory.toString and fromString. You should not be generating
them yourself.

You mean the ? Right now it's 1 milliseconds. So
that should take care of the timeouts, but what about the refused
connections?

Best practice is to schedule repair more often than GCGraceSeconds,
say weekly, rather than doing it manually when you notice the FD mark
someone dead.

This is Cassandra trying to protect itself from the load spike. You
probably need to balance your nodes, tune for performance, add
capacity, or some combination.

What's your cassandra timeout configured to? It's not uncommon to
raise that to 30sec if you're getting timeouts.

Hey Bill,
A few months ago we did an experiment with 5 hadoop nodes pulling from
4 cass nodes. It was pulling down 1 column family with 8 small columns
& just dumping the raw data to hdfs. It was cycling through around 17K
map tasks per sec. The machines weren't being taxed too hard, so I'm

I'm a bit confused WRT KeyRange's tokens in 0.7.0
When making a range query you can either use KeyRange.key or KeyRange.token.
In 0.7.0 key was typed as byte[]. tokens remain strings.
What does this string represent in case of a RP and in case of an OPP? Did

Hi all,
I'm trying to get Pig scripts to work on data in Cassandra and right now I
want to simply run the example-script.pig on a different Keyspace/CF
containing ~6'000'000 entries. I got it running but then the job aborts
after quite some time, and when I look at the logs I see hundreds of these:
I got one step further by cheating a bit, I just took all the Cassandra Jars
and dropped them into the Hadoop lib folder, so at least now I can run some
pig scripts over the data in Cassandra, but this is far from optimal since
it means I'd have to distribute my UDFs also to the Hadoop cluster, or
We have a 3-node cluster of Cassandra 0.6.4, on one of them there's a
