NamedRdds - a trait that gives you safe, concurrent creation and access to named RDDs (the native SparkContext interface only has access to RDDs by numbers).
NamedRdds - a trait that gives you safe, concurrent creation and access to named RDDs (the native SparkContext interface only has access to RDDs by numbers). It facilitates easy sharing of RDDs amongst jobs sharing the same SparkContext. If two jobs simultaneously tries to create an RDD with the same name, only one will win and the other will retrieve the same one.
Note that to take advantage of NamedRddSupport, a job must mix this in and use the APIs here instead of
the native RDD cache(), otherwise we will not know about the names.
please use NamedObjectSupport instead !
