Mck SembWever commented on CASSANDRA-2388:
------------------------------------------
Then i would hope for two separate InputFormats. One optimised for local node
connection, where cassandra is deemed the more important system over hadoop,
and another where data can be read in from anywhere. I think the latter should
be supported in some manner since users may not always have the possibility to
install hadoop and cassandra on the same servers, or they might not think it to
be so critical part (eg if CFIF is reading using a IndexClause the input data
set might be quite small and the remaining code in the m/r be the bulk of the
processing...)
> ColumnFamilyRecordReader fails for a given split because a host is down, even
> if records could reasonably be read from other replica.
