When i run bmt_example, M/R job gets executed, cassandra server gets the
data but it goes as HintedHandoff to 127.0.0.2 and it is trying to send data
to 127.0.0.2 as if 127.0.0.2 is an actual node.
Well, it kind of becomes an actual node.
Any idea, why does StorageService
returns 127.0.0.2
If you could can you please share the command line function (to load TSV)?
There is no command line function ... you have to write code for this.
and Can you please help me on storing storage-conf.xml on HDFS part?
As I said. Maybe you better start with a simpler scenario and leave
out HDFS

I wish that was true for us :)

Hey Dean ...and everyone else not managing to unsubscribe (and sending

If you don't know how to unsubscribe you can always look at the
List-Unsubscribe:

These days most of the time you will find that an -unsubscribe

I looked at the thrift service implementation and got it working.
(Much faster import!)
Thanks!

You should be using the thrift API, or a wrapper around the thrift API. It
looks like you're using internal cassandra classes.
The goal is to get around using the overhead of the Thrift API for a
bulk import.
There is a Java wrapper called Hector, and there was another talked about on

I am trying to get the bulk loading example to work for simple CF.

Also think this looks really promising.
The fact that there are so many API wrappers now (3?) doesn't reflect
well on the native API though :)

TBH while we are using super columns, the somehow feel wrong to me. I
would be happier if we could move what we do with super columns into
the row key space. But in our case that does not seem to be so easy.

I'd be quite interested to learn what you are doing with super columns
As promised on IIRC we also have collected some information as we are
seeing (probably) the same problem.

Yes, I know. And I might end up doing this in the end. I do though have
pretty hard upper limits of how many rows I will end up with for each key,
but anyways it might be a good idea none the less. Thanks for the advice on
that one.
You set count to Integer.MAX. Did you try with say 3?
Sounds like you are not using an order preserving partitioner?

Is it possible to have columns in a super column sorted by value
rather than name?
I assume not but I thought I ask anyway.
What I would love to do is something along the lines of
/user/user/country/DE += 1
and then get the sorted result of /user/user/country

We are currently working on a prototype that is using Cassandra for
realtime-ish statistics system. This seems to be quite a common use
case. If people are interested - maybe it be worth collaborating on
this beyond design discussions on the list. But first let's me explain
our approach and where
