CCE: BinSedesTuple cannot be cast to String

Question

I am trying to process the following data:

B = FOREACH A GENERATE FLATTEN( vitalStatus);
DUMB B;
(value,LIVING)
(value,LIVING)
(value,LIVING)
(value,DECEASED)
(value,LIVING)
(value,DECEASED)
(value,DECEASED)
(value,LIVING)

But when I try to filter it (FILTER A BY vitalStatus MATCHES 'DECEASED') What am I doing wrong?

I get the following error:

2013-08-23 08:47:16,290 [Thread-4] WARN  org.apache.hadoop.mapred.LocalJobRunner - job_local_0001

...

If it matters the data is coming from CqlStorage, the cassandra client for pig. — e90jimmy, Aug 23 '13 at 16:58

Resolved by applying fix from CASSANDRA-5941

As Alex Lui, mentioned in my ticket:

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.txt
ant
