Hi all.. I am pretty new to cassandra. I write a mapreduce program that read data from my cassandra columnfamily. My column value is date type but I import it in cassandra as varchar. when I specify my date column (or any other column) as source column to read the dates as map function and assign it to a column of type IColumn and execute the System.out.println(column) in shows me a lot of null.. in my log side, the map input records is correct and is the same as the number of my column family rows but others is 0.. also, my columnfamily has 12 columns. I try this mapreduce program with a smaller table hat has about 2 or 3 columns and it works and print the column and column values. but it didn't work with my table.. what should I do? may the problem is from the number of columns? thanks..
