Minimum configuration for a hadoop connection to a cluster?

What's the minimum cluster information required to uniquely identify a mapr cluster in a Configuation instance?

 

Normally the java code would use a line like Configuration conf = new Configuration();

 

Which will pick up the hadoop setting from the /opt/mapr/conf/*.xml files.

 

But what happens if I want a client to connect to two different clusters?

I would have to set the configuration parameters separately.

Which parameters are required and which ones are going to be mapr specific?

(Apache doesn't have a CLDB ...)

 

My goal is to look at both MapRFS on each cluster... and I don't want to have to rely on NFS mounting of both clusters locally.


Any sample code snippets?


TIA
