Description

From http://thread.gmane.org/gmane.comp.db.cassandra.user/20039

Cassandra-0.8.4 w/ ByteOrderedPartitioner

CFIF's inputSplitSize=196608

3 map tasks (from 4013) is still running after read 25 million rows.

Can this be a bug in StorageService.getSplits(..) ?

getSplits looks pretty foolproof to me but I guess we'd need to add
more debug logging to rule out a bug there for sure.

I guess the main alternative would be a bug in the recordreader paging.
