save the received data to the Wal (the Wal log can be stored on HDFS), so we can recover from the Wal when it fails, without losing the data.Below, I'll show you how to use this method to receive data.　　1, the introduction of dependency.For Scala and Java projects, you can introduce the following dependencies in your Pom.xml file:If you are using SBT, you can introduce:Librarydependencies + = "Org.apache.spark"% "spark-streaming-kafka_2.10"% "1.3.0"　

In the development process, the use of third-party excellent relying on the library is a very common problem, sometimes maven, or gradle, or SBT, most of the library project, will have the corresponding Gradle,maven-dependent code, but some do not, especially the use of snapshot dependencies, Although the source code can be down, and then source-level dependency, or their own export jar dependencies, this time, artifact Jitpack appeared.Use ash often

Most of the time, we need to package the program we're writing, and at this point we can build tools like Maven, SBT, Ant, and so on, where I'm using maven.Packaged into a jar package that can have a main class (no dependencies in the jar package)The following is a jar package that is packaged as executable with the main class:Project> ...Build>Plugins>Plugin>Groupid>org.apache.maven.pluginsGroupid>Artifactid>maven-jar-pluginArtifactid> ...Configurati

Submitting applicationsScripts in the script in Spark bin directory are spark-submit used with the launch application on the cluster. It can use all Spark-supported cluster managers through a single interface, so you don't need to configure your application specifically for each cluster managers.Packaging app DependenciesIf your code relies on other projects, in order to distribute the code into the Spark cluster you will need to package them with your application. To do this, create a assembly

, use method Streamingcontext.actorstream (Actorprops, Actor-name). Spark Streaming uses the Streamingcontext.queuestream (Queueofrdds) method to create an RDD queue-based DStream, and each RDD queue is treated as a piece of data stream in DStream. 2.2.2.2 Advanced Sources This type of source requires an interface to an external Non-spark library, some of which have complex dependencies (such as Kafka, Flume).

DStream, and each RDD queue is treated as a piece of data stream in DStream. 2.2.2.2 Advanced Sources This type of source requires an interface to an external Non-spark library, some of which have complex dependencies (such as Kafka, Flume). Therefore, creating dstreams from these sources requires a clear dependency. For example, if you want to create a dstream stream of data that uses Twitter tweets, you must follow these steps: 1) Add spark-streaming-twitter_2.10 dependency in
