Helper object defining how to accumulate values of a particular type.
A simpler version of
:: Experimental :: A future for the result of an action to support cancellation.
:: DeveloperApi :: Utility trait for classes that want to log data.
A partition of an RDD.
:: DeveloperApi :: Various possible reasons why a task ended.
A data type that can be accumulated, ie has an commutative and associative "add" operation, but where the result type,
A simpler value of
:: DeveloperApi :: A set of functions used to aggregate data.
:: Experimental :: A
:: DeveloperApi :: Base class for dependencies.
:: DeveloperApi :: The task failed because the executor that it was running on was lost.
:: DeveloperApi :: An iterator that wraps around an existing iterator to provide task killing functionality.
:: 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.
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.
|SerializableWritable<T extends org.apache.hadoop.io.Writable>|
:: DeveloperApi :: Represents a dependency on the output of a shuffle stage.
:: Experimental :: A
Configuration for a Spark application.
Main entry point for Spark functionality.
:: 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.
Resolves paths to files added through
:: DeveloperApi :: Contextual information about a task which can be read or mutated during execution.
:: 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.
:: DeveloperApi :: Exception thrown when a task is explicitly killed (i.e., task failure is expected).
