I think you need to send that details file for us to give you more
information:
/home/hduser/apache-cassandra-2.0.9/examples/pig/pig_1406808480077.log
pig stores its runtime exceptions in a main details file that has the guts
of the problem.
Also, try posting to the pig user list.

Thanks Jeremy! Maybe figuring out how to do paging in pig would have been
easier, but I found the widerow setting first which led me where I am
today. I don't mind helping to blaze trails, or contribute back when doing
so, but I usually try to follow rather than lead when it comes to
tools/softwa
For our use case, we had a lot of narrow column families and the couple of
column families that had wide rows, we did our own paging through them. I
don't recall if we did paging in pig or mapreduce but you should be able to do
that in both since pig allows you to specify the slice start.

If you don't mind me asking, how are you handling the fact that pre-widerow
you are only getting a static number of columns per key (default 1024)? Or
am I not understanding the "limit" concept?

The Dachis Group (where I just came from, now at DataStax) uses pig with
cassandra for a lot of things. However, we weren't using the widerow
implementation yet since wide row support is new to 1.1.x and we were on 0.7,
then 0.8, then 1.0.x.
I think since it's new to 1.1's hadoop support, it s

It'd be great if we had different settings for inter- and intra-DC read repair.

Yes - the HadoopSupport should be updated for the functionality that is added
to 0.7. It's still a little in flux. There is an output format and output
streaming support on trunk/0.7 beta2. The output format has a java example in
the contrib/word_count example code. The output streaming, whi
AFAIK you can submit a pig job to the Hadoop job server via the pig command
line interface. If you have not done so already have a read of the Hadoop Book
it discusses pig as well

Not sure how you go about monitoring the hadoop job though.

Can't you just execute a Pig script with PHP by calling Pig with a PHP exec
function call? I'm not sure what you're trying to do with it, but that's one
way you could do it.
> PIG: there is a LoadFunc
Pig do not have thrift interface, But I believe you can create it. And
another way I think is create a web service for your pig service, and
call the web service in your php.

Hi,
PHP: I basicaly need to start pig program from a php script (via thrift or
something..?)
PIG: there is a LoadFunc that loads data from Cassandra, is there also a
StoreFunc?

I am using Pig v0.7 and Cassandra v0.6.5. The example that comes
bundles up in Cassandra under contrib/pig uses unframed by default. When
I use the default configuration for Cassandra then the Pig contrib works
as expected. However when I change the configuration to framed then pig

I don't think you can (although in 0.7 framed is the default for Pig
like everything else).

Thanks Jonathan. I have this part figured out now :)
Can you explain to me how I can get this to work with Framed support. It
just hangs now and doesn't return anything

Hi
did you register cassandra jars with Pig. This seems like a class
loading problem.

I am trying do a basic load:
rows = LOAD 'cassandra://Foo/Bar' USING CassandraStorage();
Details of basic linkage are in the contrib/pig section of the
Cassandra source in the readme. You should be able to run basic
queries with just that.
