Multiple people have expressed an interest in 'hadoop integration' and
'map/reduce functionality' within Cassandra. I'd like to get a feel
for what that means to different people.
As a starting point for discussion, Jeff Hodges undertook a prototype
effort last summer which was the subject
let it be part of the InputSplit calculation.
3) Progress information should be calculated and displayed.

I agree with what Jeff says here about RandomPartitioner support being key.
+1
For my purposes with map/reduce I'd personally be fine with some
general all-keys dump utility that wrote contents of one node to a
file,

bin/sstablekeys will dump just the keys from an sstable without row
deserialization overhead, but it can't introspect a commitlog.

Yes, and will it not also return the keys that are replicas from
ranges
sstablekeys is really the wrong place to support m/r anyway, it just
shows that the index can handle what m/r will need

Hello!
Has anyone tried to run MapReduce analytics on data stored in Cassandra? I feel
like I saw a patch once to get hadoop working on top of Cassandra, but I can't
find it now. I know that Hadoop integration is big on people's wishlists for
future versions of Cassandra, but I'm just curious
AH, there we go. Thanks a lot Ryan!
