Mck SembWever commented on CASSANDRA-3150:
------------------------------------------
There's a lot to learn about cassandra so forgive my ignorance in so many areas.
So how can {{StorageService.getSplits(..)}} be so out of whack? Is there
anything i can tune to better this situation?
(Or is there any other debug i can provide?)

> bq. Cassandra-0.8.4 w/ ByteOrderedPartitioner
> bq. CFIF's inputSplitSize=196608
> bq. 3 map tasks (from 4013) is still running after read 25 million rows.
> bq. 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.
