InsightEdge Examples

This repository contains example InsightEdge applications.

Requirements

  • Java 1.8
  • Scala 2.10
  • Maven 3.1+
  • SBT 0.13.9+ (optional)
  • InsightEdge distribution

Building project

InsightEdge jars are not published to Maven Central Repository yet. To install artifacts to your local Maven repository, make sure you have Maven installed and then run the following from InsightEdge directory:

# Linux:
./insightedge/tools/maven/insightedge-maven.sh

# Windows:
insightedge\tools\maven\insightedge-maven.cmd

This project has both SBT and Maven build files. You can build it with the next commands:

# Maven
mvn clean test package

# SBT
sbt clean test assembly

Running examples

There are several options how you can run examples:

  • from Web Notebook
  • from your IDE
  • from a command line

Configure insightedge/bin/setenv-overrides

Linux

Add to /insightedge/bin/setenv-overrides.sh:

export SPARK_LOCAL_IP=127.0.0.1
Windows

Add to /insightedge/bin/setenv-overrides.bat:

set SPARK_LOCAL_IP=127.0.0.1

Starting local environment

Prior to executing example application, you have to start the Data Grid and deploy an empty space on it. You can do it using demo mode:

# Linux:
./insightedge/bin/insightedge demo

# Windows:
insightedge\bin\insightedge.bat demo

Such command will start next components:

  • Spark master at spark://127.0.0.1:7077 and Spark slave
  • Spark monitoring UI at 127.0.0.1:8080
  • Data Grid manager and two containers with 1G heap each
    • space is deployed with name insightedge-space

Web Notebook

The interactive Web Notebook (based on Zeppelin) is started automatically in demo mode at http://127.0.0.1:8090. For more information, refer to 'Zeppelin Notebook' section in InsightEdge documentation

Running from IDE

You can run examples from your favourite IDE. Every example has a main method, so it can be executed as standard application. There two important things:

  • enable run-from-ide maven profile (this will switch required dependencies to compile scope so they are available in classpath)
  • spark master url should be set to local[*] so that Spark is started in embedded mode

Here is an example of run configuration for SaveRDD for Intellij Idea: IDEA run configuration

With this configuration, example will run on local Spark cluster and save the generated RDD to Data Grid to specified space.

Running from command line

You can build the project and submit examples as Spark applications with the next command:

# Linux:
./insightedge/bin/insightedge-submit --class {main class name} --master {Spark master URL} \
    {insightedge-examples.jar location} \
    {Spark master URL} {space name} {lookup group} {lookup locator}

# Windows:
insightedge\bin\insightedge-submit --class {main class name} --master {Spark master URL} ^
    {insightedge-examples.jar location} ^
    {Spark master URL} {space name} {lookup group} {lookup locator}

For example, SaveRDD can be submitted with the next syntax:

# Linux:
./insightedge/bin/insightedge-submit --class org.insightedge.examples.basic.SaveRdd --master spark://127.0.0.1:7077 \
    ./insightedge/examples/jars/insightedge-examples.jar

# Windows:
insightedge\bin\insightedge-submit --class org.insightedge.examples.basic.SaveRdd --master spark://127.0.0.1:7077 ^
    insightedge\quickstart\scala\insightedge-examples.jar

If you are running local cluster with default settings (see Running Examples), you can omit arguments:

# Linux:
./insightedge/bin/insightedge-submit --class {main class name} --master {Spark master URL} \
    {insightedge-examples.jar location}

# Windows:
insightedge\bin\insightedge-submit --class {main class name} --master {Spark master URL} ^
    {insightedge-examples.jar location}

Note that running TwitterPopularTags example requires you to pass Twitter app tokens as arguments

Python examples

You can run Python examples with

# Linux:
./insightedge/bin/insightedge-submit --master {Spark master URL} {path to .py file}

# Windows:
insightedge\bin\insightedge-submit --master {Spark master URL} {path to .py file}

For example,

# Linux:
./insightedge/bin/insightedge-submit --master spark://127.0.0.1:7077 ./quickstart/python/sf_salaries.py

# Windows:
insightedge\bin\insightedge-submit --master spark://127.0.0.1:7077 quickstart\python\sf_salaries.py

Stopping local environment

open version

Ctrl C

Premium version

To stop all InsightEdge components, next command can be executed: ./insightedge/bin/insightedge.bat host kill-agent
