Description
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..
