About python streaming using Cassandra as input

2011-05-09 Thread Danhang Tang 
Hi all,

I've been trying to apply this patch to Cassandra but ran into some errors.
https://issues.apache.org/jira/browse/CASSANDRA-1497

The comments said it's fixed for version 0.7.1. But I can't directly apply
it to this version. So I apply it manually to the java files in hadoop
package. Compiling was successful. But then when executing the
hadoop_streaming_input
I encountered a runtime error:

11/05/06 17:27:21 WARN conf.Configuration: mapred.job.tracker is deprecated.
Instead, use mapreduce.jobtracker.address

packageJobJar: [./bin/../../../interface/avro/cassandra.avpr,
./bin/mapper.py, ./bin/reducer.py,

Any ideas?

Thanks,

Re: About python streaming using Cassandra as input

2011-05-09 Thread Jonathan Ellis 
You'll have a lot more luck w/ pig or hive as a high-level hadoop
client, than python.  Certainly until 1470 is done for real.

Brisk does the hadoop-on-cassandra integration for you:

Re: About python streaming using Cassandra as input

2011-05-09 Thread Jeremy Hanna 
pig/hive/brisk are certainly great ways of doing mapreduce with cassandra.

I had written the patch to 1497 last Fall and it didn't quite work then.  I had 
meant to get back to it, but since then I've changed jobs and have been really 
busy there.

I do like how the patch abstracts the CFIF/CFRR so that it could be pluggable 
with different formats - like avro or others.  That would make it possible to 
plug it in more easily into dumbo - https://github.com/klbostee/dumbo/wiki/ for 
instance.  It has an abstract parent that does all of the Cassandra heavy 
lifting and each child only does things specific to avro or etc.

If anyone wants to get the patch working against current 0.7-branch, I wouldn't 
mind answering questions about it.  I just don't currently have time to rebase 
and get it working.  I would only take the idea and structure from the patch 
and use as much of 0.7-branch code as possible.  Doing that, it should be 
fairly straightforward as it just adds older mapred package method support and 
abstracts out the Cassandra specific bits.
