> I noticed when running locally some examples with the Scala API that the TaskManagers
ran out of network buffers when increasing the number of slots on one machine. Trying to adjust
the value, I stumbled across a more naturally grown interface in LocalExecutor and NepheleMiniCluster.
Some parameters are specified as attributes of NepheleMiniCluster, others are loaded from
a configuration file and others use the default value specified in ConfigConstants. I think
it would be good to give the user the ability to easily control the different parameters in
a unified fashion by providing a configuration object. Furthermore, the NepheleMiniCluster
is not consistent with the use of parameter values: For example, getJobClient sets the jobmanager
rpc port with respect to the attribute jobManagerRpcPort whereas the start method can retrieve
it from a specified configuration file.
