Jonathan Ellis commented on CASSANDRA-3150:
-------------------------------------------
bq. a gap so small there exists no rows in between
Right. So you page through with startToken increasing, until either you hit
endToken or you get no rows back.
(Recall that the rows from get_range_slices come back in token order.)
> ColumnFormatRecordReader loops forever

> 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.
