Eris Nuts

RDDs (resilient distributed datasets) achieve fault tolerance through a notion of lineage: if a partition of an RDD is lost, the RDD has enough information about how it was derived from other RDDs to be able to rebuild just that partition.

A new model of cluster computing has become widely

popular, in which data-parallel computations are executed

on clusters of unreliable machines by systems that automatically

provide locality-aware scheduling, fault tolerance,

and load balancing
