Subject Hadoop kills Cassandra
Date Mon, 27 Jan 2014 22:57:01 GMT
For some reason when my map-reduce job is almost complete, all mappers (~40) begin to connect
to a single Cassandra node. This noe then die due to Java Heap space error.

It looks like Hadoop is misconfigured. Valid behavior for me:

Each mapper should iterate only a local node. How can I configure mappings between hadoop
mappers and Cassandra nodes?
