Heya!
I am seeing something rather strange in the way Cass 1.2 + Pig seem to handle
integer values.
Setup: Cassandra 1.2.10, OSX 10.8, JDK 1.7u40, Pig 0.11.1. Single node for
testing this.
First a table:
CREATE TABLE testc (
key text PRIMARY KEY,
ivalue int,
svalue text,

this is the issue:

cant really reproduce, could you update the ticket with a bit more info
about your setup?
do you have multiple .json files in your data dirs?

Nulls should definitely stay null (that's an old DB debate), but if this
is a generic case, we might consider adding an emptyValue() helper method.
Would that be possible Sylvain?

Hello.
I have been looking into the memory patterns of Cassandra (1.1.5), and I have a
suggestion that I haven't seen discussed here.
Cassandra is configured by default with a GC tailored for pauseless operation
instead of throughput, and this makes sense since it needs to answer client
In fact, the blog post on the subject (
http://www.datastax.com/dev/blog/simple-data-importing-and-exporting-with-cassandra)
also states that the NULL option only is used by the COPY ... TO command
but it also states that this might change in the future and the future
seems to be here now.

Same is true if started from 1.2.9 version to 2.0.x
Seems like Cassandra-5383 is the related issue.
The code in the function mutateLevel (from 1.2.5 to 1.2.9 and later ) is
indirectly using the java file::renameTo function. And that will not work on
Windows if the file already exists. Don't

Hi Marcus,
I've seen your patch. This works with what I'm seeing. The first data

As a workaround I've made sure that each of the snapshot directories now

Did a test for File::rename on Ubuntu and windows.
Seems that on Ubuntu the File::renameTo(FROM, TO) is actually replacing the

So that would make it a problem only on Windows. Adding a File::delete before

I know that CqlStorage and AbstractCassandraStorage got changed for 1.2.10

Thank you, both Michael and Robert for your suggestions. I actually saw 5760,

That said, I noticed that my Chef scripts were failing to set the

boradcast_address is only needed when you are going cross region (IIRC it's the
EC2MultiRegionSnitch) that sets it.
As rob said, make sure the seed list includes on of the other

Hi Aaron, thanks for the clarification.
As might be expected, having the broadcast_address fixed hasn't fixed anything.
