Description

I have 7 suse nodes running Cassandra0.7 branch (latest as of the morning of Nov 9). I've loaded 10 rows with one column family(replication factor=4) and 100 super columns. Using the ColumnFamilyInputFormat with mapreduce (LocalJobRunner) to retrieve all the rows gives me the following exception:

Any help would be appreciated.
