{noformat}
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:

10/11/10 10:33:15 WARN mapred.LocalJobRunner: job_local_0001
