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.
I'll tell yo
Hello,
I am trying to integrate cassandra into Hadoop and PIG and trying to load
CSV file into Cassandra using PIG Script. Can someone help ?
root@hadoop-1:/home/hduser/apache-cassandra-2.0.9/examples/pig# cat
pigCasandra.pig
data = LOAD 'example.csv' using PigStorage(',') AS (row_id: chararray,
filters on the columns which are part of
partition key. This seems to be very basic requirement to have for C*-Pig
integration.
To give you more idea on the problem, here is the jira on the same topic.

I'm using AWS's EMR (hadoop as a service), and one step copies some data
from EMR -> my cassandra cluster. I used to patch EMR with pig 0.11, but
now AWS officially supports 0.11, so I thought I'd give it a try. I was
having issues. The AWS forum on it is here:

worked as well and output to cassandra.
So I suspect that for some reason your environment is messed up somehow - the
CassandraStorage class (for pig integration) doesn't point to TypeParser in
0.8.0.
create keyspace pygmalion;
use pygmalion;
create column family account with comparator = UTF

PIG integration with 0.8.0 is no longer working / doesn't work with
0.8.0 release, but will with 0.8.1 .. fair
Yes ... I ran an "ant" in the root directory on a fresh download of 0.8.0 src:

Been trying for the past little bit to try and get the PIG integration
working with Cassandra 0.8.0
1. Downloaded the src for 0.8.0 and ran ant build
2. went into contrib/pig and ran ant ... gives me:
/usr/local/src/apache-cassandra-0.8.0-src/contrib/pig/build/cassandra_storage.jar

Does anyone try to get data from Super column family using grunt shell? The
example pig script explains how to analyze data for standard column family.
