A data type that can be accumulated, ie has an commutative and associative "add" operation,
but where the result type,
R, may be different from the element type being added,
Helper object defining how to accumulate values of a particular type.
A simpler value of Accumulable where the result type being accumulated is the same as the types of elements being merged, i.
A simpler version of org.apache.spark.AccumulableParam where the only data type you can add in is the same type as the accumulated value.
:: DeveloperApi :: A set of functions used to aggregate data.
:: Experimental :: A FutureAction for actions that could trigger multiple Spark jobs.
:: DeveloperApi :: Base class for dependencies.

:: DeveloperApi :: An iterator that wraps around an existing iterator to provide task killing functionality.
:: DeveloperApi :: Utility trait for classes that want to log data.
:: DeveloperApi :: Base class for dependencies where each partition of the parent RDD is used by at most one partition of the child RDD.
:: DeveloperApi :: Represents a one-to-one dependency between partitions of the parent and child RDDs.
A partition of an RDD.
An object that defines how the elements in a key-value pair RDD are partitioned by key.
:: DeveloperApi :: Represents a one-to-one dependency between ranges of partitions in the parent and child RDDs.
A org.apache.spark.Partitioner that partitions sortable records by range into roughly equal ranges.

:: DeveloperApi :: Holds all the runtime environment objects for a running Spark instance (either master or worker), including the serializer, Akka actor system, block manager, map output tracker, etc.
:: DeveloperApi :: Contextual information about a task which can be read or mutated during execution.
:: DeveloperApi :: Various possible reasons why a task ended.
:: DeveloperApi :: Exception thrown when a task is explicitly killed (i.
:: DeveloperApi :: The task failed because the executor that it was running on was lost.
The SparkContext object contains a number of implicit conversions and parameters for use with various Spark features.
Resolves paths to files added through
:: DeveloperApi :: The task finished successfully, but the result was lost from the executor's block manager before it was fetched.
:: DeveloperApi :: We don't know why the task ended -- for example, because of a ClassNotFound exception when deserializing the task result.
