:: DeveloperApi :: A set of functions used to aggregate data.
A FutureAction for actions that could trigger multiple Spark jobs.
:: DeveloperApi :: Base class for dependencies.
:: DeveloperApi :: Task failed due to a runtime exception.
:: DeveloperApi :: The task failed because the executor that it was running on was lost.
:: DeveloperApi :: Task failed to fetch shuffle data from a remote node.
A future for the result of an action to support cancellation.
A org.apache.spark.Partitioner that implements hash-based partitioning using
Java's Object.hashCode
.
:: DeveloperApi :: An iterator that wraps around an existing iterator to provide task killing functionality.
Handle via which a "run" function passed to a ComplexFutureAction can submit jobs for execution.
:: DeveloperApi :: Base class for dependencies where each partition of the child RDD depends on a small number of partitions of the parent RDD.
:: DeveloperApi :: Represents a one-to-one dependency between partitions of the parent and child RDDs.
An identifier for a partition in 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 :: Represents a dependency on the output of a shuffle stage.
A FutureAction holding the result of an action that triggers a single job.
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, RpcEnv, block manager, map output tracker, etc.
Low-level status reporting APIs for monitoring job and stage progress.
:: DeveloperApi :: Task requested the driver to commit, but was denied.
Contextual information about a task which can be read or mutated during execution.
:: DeveloperApi :: Various possible reasons why a task ended.
:: DeveloperApi :: Various possible reasons why a task failed.
:: DeveloperApi :: Task was killed intentionally and needs to be rescheduled.
:: DeveloperApi :: Exception thrown when a task is explicitly killed (i.
A data type that can be accumulated, i.
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 org.apache.spark.scheduler.ShuffleMapTask
that completed successfully earlier, but we
lost the executor before the stage completed.
The SparkContext object contains a number of implicit conversions and parameters for use with various Spark features.
Resolves paths to files added through SparkContext.addFile()
.
:: DeveloperApi :: Task succeeded.
:: 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.
Spark's broadcast variables, used to broadcast immutable datasets to all nodes.
Executor components used with various cluster managers.
IO codecs used for compression.
This package implements Spark's memory management system.
