| | | | | | | | | | Since they rely on println to display results, we need to first collect those results to the driver to have them actually display locally.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MQTT Adapter for Spark Streaming MQTT is a machine-to-machine (M2M)/Internet of Things connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. You may read more about it here http://mqtt.org/ Message Queue Telemetry Transport (MQTT) is an open message protocol for M2M communications. It enables the transfer of telemetry-style data in the form of messages from devices like sensors and actuators, to mobile phones, embedded systems on vehicles, or laptops and full scale computers. The protocol was invented by Andy Stanford-Clark of IBM, and Arlen Nipper of Cirrus Link Solutions This protocol enables a publish/subscribe messaging model in an extremely lightweight way. It is useful for connections with remote locations where line of code and network bandwidth is a constraint. MQTT is one of the widely used protocol for 'Internet of Things'. This protocol is getting much attraction as anything and everything is getting connected to internet and they all produce data. Researchers and companies predict some 25 billion devices will be connected to the internet by 2015. Plugin/Support for MQTT is available in popular MQs like RabbitMQ, ActiveMQ etc. Support for MQTT in Spark will help people with Internet of Things (IoT) projects to use Spark Streaming for their real time data processing needs (from sensors and other embedded devices etc).

* Change build and run instructions to use assembliesMatei Zaharia2013-08-293-0/+447
| | | | | | | | | | | | | | | | This commit makes Spark invocation saner by using an assembly JAR to find all of Spark's dependencies instead of adding all the JARs in lib_managed. It also packages the examples into an assembly and uses that as SPARK_EXAMPLES_JAR. Finally, it replaces the old "run" script with two better-named scripts: "run-examples" for examples, and "spark-class" for Spark internal classes (e.g. REPL, master, etc). This is also designed to minimize the confusion people have in trying to use "run" to run their own classes; it's not meant to do that, but now at least if they look at it, they can modify run-examples to do a decent job for them. As part of this, Bagel's examples are also now properly moved to the examples package instead of bagel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds Java examples and unit tests for all GLM algorithms to make sure the MLLib interface works from Java. Changes include - Introduce LabeledPoint and avoid using Doubles in train arguments - Rename train to run in class methods - Make the optimizer a member variable of GLM to make sure the builder pattern works

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Changes ALS to accept RDD[Rating] instead of (Int, Int, Double) making it easier to call from Java - Renames class methods from `train` to `run` to enable static methods to be called from Java. - Add unit tests which check if both static / class methods can be called. - Also add examples which port the main() function in ALS, KMeans to the examples project. Couple of minor changes to existing code: - Add a toJavaRDD method in RDD to convert scala RDD to java RDD easily - Workaround a bug where using double[] from Java leads to class cast exception in KMeans init
