Johan Oskarsson updated CASSANDRA-955:
--------------------------------------
Attachment: CASSANDRA-955.patch
Looks up the hostname from the ipaddress in order to have Hadoop schedule the
tasks as close to the data as possible. This is done from where the Hadoop job
is scheduled and not on Cassandra.
> Hadoop doesn't schedule the tasks close to the data

> Hadoop relies on locations for data in input splits being represented as
> hostnames and not ip addresses. Currently in my testing tasks are more often
> then not being scheduled on a node that does not contain the data requested.
