command line with cassandra

how can i pass the value as command line arguments in Cassandra PIG Script.

Below line for syntax for execute the PIG Script

{apache-cassandra-0.4.0-src path}/contrib/pig/bin/pig_cassandra –param argument = Value script.pig

then i got the below error [main] INFO org.apache.pig.Main - Logging error messages to: /home/ec2-user/apache-cassandra-0.7.4-src/contrib/pig/pig_1302092850679.log [main] ERROR org.apache.pig.Main - ERROR 2999: Unexpected internal error.

thanks in advance

The source for pig_cassandra shows

export PIG_OPTS=$PIG_OPTS" -Dudf.import.list=org.apache.cassandra.hadoop.pig"
cat "$cwd/../build/bootstrap.pig" - | $PIG_HOME/bin/pig $*

Did you try

-param argument=Value script.pig
