You're trying to use FromCqlColumn on a tuple that has been flattened. The
schema still thinks it's {title: chararray}, but the flattened tuple is now
two values. I don't know how to retrieve the data values in this case.
Your code will work correctly if you do this:
*values3 = FOREACH rows GENERA
Hi
1.-
May be?
-- Register the UDF
REGISTER /path/to/cqlstorageudf-1.0-SNAPSHOT
-- FromCqlColumn will convert chararray, int, long, float, double
DEFINE FromCqlColumn com.megatome.pig.piggybank.tuple.FromCqlColumn();
-- Load data as normal
data_raw = LOAD 'cql://bookcrossing/books' USING CqlS
hi all:
More info :
https://issues.apache.org/jira/browse/CASSANDRA-5941
I tried this (and gen. cassandra 1.2.9) but do not work for me,
git clone http://git-wip-us.apache.org/repos/asf/cassandra.git
cd cassandra
git checkout cassandra-1.2
patch -p1 < 5867-bug-fix-filter-push-down-1.2-branch
*good/nice job !!!*

*I'd testing with an udf only with string schema type this is better and
elaborate work..*

I threw together a quick UDF to work around this issue. It just extracts
the value portion of the tuple while taking advantage of the CqlStorage
generated schema to keep the type correct.
You can get it here: https://github.com/iamthechad/cqlstorage-udf
I'll see if I can find more useful informat
I try this:
*rows = LOAD
'cql://keyspace1/test?page_size=1&split_size=4&where_clause=age%3D30' USING
CqlStorage();*
*dump rows;*
*ILLUSTRATE rows;*
*describe rows;*
*
*
*values2= FOREACH rows GENERATE TOTUPLE (id) as
(mycolumn:tuple(name,value));*
*dump values2;*
*describe values2;*

hi Chad .
I have this issue
I send a mail to user-pig-list and I still i can resolve this, and I can
not access to column values.
In this mail I write some things that I try without results... and
information about this issue.

(I'm using Cassandra 1.2.8 and Pig 0.11.1)
I'm loading some simple data from Cassandra into Pig using CqlStorage. The
CqlStorage loader defines a Pig schema based on the Cassandra schema, but
it seems to be wrong.
If I do:
data = LOAD 'cql://bookdata/books' USING CqlStorage();
DESCRIBE data;
