All Implemented Interfaces:
org.apache.spark.internal.Logging
public class StreamingContext extends Object implements org.apache.spark.internal.Logging
Deprecated.
This is deprecated as of Spark 3.4.0. There are no longer updates to DStream and it's a legacy project. There is a newer and easier to use streaming engine in Spark called Structured Streaming. You should use Spark Structured Streaming for your streaming applications.
Main entry point for Spark Streaming functionality. It provides methods used to create DStreams from various input sources. It can be either created by providing a Spark master URL and an appName, or from a org.apache.spark.SparkConf configuration (see core Spark documentation), or from an existing org.apache.spark.SparkContext. The associated SparkContext can be accessed using context.sparkContext. After creating and transforming DStreams, the streaming computation can be started and stopped using context.start() and context.stop(), respectively. context.awaitTermination() allows the current thread to wait for the termination of the context by stop() or by an exception.

      Deprecated.
      Create a new DStream in which each RDD is generated by applying a function on RDDs of the DStreams.
      Parameters:
      dstreams - (undocumented)
      transformFunc - (undocumented)
      evidence$16 - (undocumented)
      Returns:
      (undocumented)

    • addStreamingListener

      public void addStreamingListener(StreamingListener streamingListener)
      Deprecated.
      Add a StreamingListener object for receiving system events related to streaming.
      Parameters:
      streamingListener - (undocumented)

    • removeStreamingListener

      public void removeStreamingListener(StreamingListener streamingListener)
      Deprecated.

    • getState

      public StreamingContextState getState()
      Deprecated.
      :: DeveloperApi ::

      Return the current state of the context. The context can be in three possible states -

      - StreamingContextState.INITIALIZED - The context has been created, but not started yet. Input DStreams, transformations and output operations can be created on the context. - StreamingContextState.ACTIVE - The context has been started, and not stopped. Input DStreams, transformations and output operations cannot be created on the context. - StreamingContextState.STOPPED - The context has been stopped and cannot be used any more.

      Returns:
      (undocumented)

    • start

      public void start()
      Deprecated.
      Start the execution of the streams.

      Throws:
      IllegalStateException - if the StreamingContext is already stopped.

    • awaitTermination

      public void awaitTermination()
      Deprecated.
      Wait for the execution to stop. Any exceptions that occurs during the execution will be thrown in this thread.

    • awaitTerminationOrTimeout

      public boolean awaitTerminationOrTimeout(long timeout)
      Deprecated.
      Wait for the execution to stop. Any exceptions that occurs during the execution will be thrown in this thread.

      Parameters:
      timeout - time to wait in milliseconds
      Returns:
      true if it's stopped; or throw the reported error during the execution; or false if the waiting time elapsed before returning from the method.

    • stop

      public void stop(boolean stopSparkContext)
      Deprecated.
      Stop the execution of the streams immediately (does not wait for all received data to be processed). By default, if stopSparkContext is not specified, the underlying SparkContext will also be stopped. This implicit behavior can be configured using the SparkConf configuration spark.streaming.stopSparkContextByDefault.

      Parameters:
      stopSparkContext - If true, stops the associated SparkContext. The underlying SparkContext will be stopped regardless of whether this StreamingContext has been started.

    • stop

      public void stop(boolean stopSparkContext, boolean stopGracefully)
      Deprecated.
      Stop the execution of the streams, with option of ensuring all received data has been processed.

      Parameters:
      stopSparkContext - if true, stops the associated SparkContext. The underlying SparkContext will be stopped regardless of whether this StreamingContext has been started.
      stopGracefully - if true, stops gracefully by waiting for the processing of all received data to be completed
