What's your cassandra timeout configured to? It's not uncommon to
raise that to 30sec if you're getting timeouts.

Hey Bill,
A few months ago we did an experiment with 5 hadoop nodes pulling from
4 cass nodes. It was pulling down 1 column family with 8 small columns
& just dumping the raw data to hdfs. It was cycling through around 17K
map tasks per sec. The machines weren't being taxed too hard, so I'm
sure t
There's a good post on stackoverflow comparing the two

It seems to me that both projects have pretty vibrant communities behind them.

The cassandra column family input format will go over a an entire
column family sending a slice of a row into a mapper at a time. From
there there's a lot you can do. As far as how you aggregate data
together, I'd suggest experimenting with the latest version of Pig
which thankfully supports the ne
Hi, I'm running cassandra .6.2 on a dedicated 4 node cluster and I
also have a dedicated 4 node hadoop cluster. I'm trying to run a
simple map reduce job against a single column family and it only takes
32 map tasks before I get floods of thrift timeouts. That would make
sense to me if the cassandr
