> Enhance hadoop support to take a list of hosts for the initial connection
> -------------------------------------------------------------------------

> Key: CASSANDRA-2378
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2378
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Jeremy Hanna
> Assignee: Jeremy Hanna
> Labels: hadoop
>
> Currently the hadoop configuration accepts a host to do the initial
> connection - from there it spreads the load around the ring with the input
> splits. Using rrdns with retry logic would be fine externally, but it would
> be nice to have something built-in to handle multiple hosts. So as we talked
> about in the channel, the cassandra hadoop config variable for cassandra host
> could accept a comma separated list of hosts that it could try for the
> initial connection. It could hit a random host and if that timed out, try
> another host and return an error to the calling client if it couldn't succeed
> with any of the hosts.
