------------------------------------

             Summary: Caused by: InvalidRequestException(why:Invalid restrictions)
                 Key: CASSANDRA-6502
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6502
             Project: Cassandra
          Issue Type: Bug
          Components: API, Core, Hadoop
         Environment: CentOS release 6.4
            Reporter: Akshay DM


I am using Cassandra 1.2.10 and have a primary key column which is of timestamp datatype.
Now I am trying to retrieve the data for the date ranges. Since we know we can't use between
clause, we are using greater than(<) and less than(>) to get the date ranges. This perfectly
seems to work in cassandra's cqlsh. But with pig_cassandra integration, it throws an error.
Here is the load function.

filteredData = LOAD 'cql://<keyspace>/<columnfamily>?where_clause=time1%3E1357054841000590+and+time1%3C1357121822000430'
USING org.apache.cassandra.hadoop.pig.CqlStorage();

Here is the error it throws..
