Efficient way of figuring out which nodes a set of keys belong to - Hadoop integration

2011-09-22 Thread Tharindu Mathew
Hi, I managed to modify the Hadoop-Cassandra integration to start with a column of a CF used for indexing. In the map phase, I get keys from different CFs and get the row I need. So this all works fine, for a single node. :) I'd like to effectively identify a set of nodes for a set of rows and ge

Hi everyone, I'm interested in contributing to Cassandra in my spare time. Any areas that is of interest to the project that I can look into (that leaves enough time for a learning curve :) ? I already have the source checked out and built on my machine. -- Regards, Tharindu
