The examples directory contains smaller code examples that demonstrate how-to take advantage of various Spark capabilities such as streaming, ML, from a Node.js environment. There is also an examples/server directory that contains smaller code examples that can be run directly on the EclairJS server.
The eclairs-examples repository contains a number of relatively full-function example Node.js applications that include UIs using the EclairJS client, plus the EclairJS server and Spark.
Try The Examples
To try the examples, you will need the example code, a client, and a server. An easy way to obtain the code and a client is to download a copy of the EclairJS repository by clicking the "Clone or download" button above. Then bring up a command line and do the following to install a client:
cd repository-root-dir/examples npm install
We have provided the server in a Docker container which you can obtain and run with:
docker pull eclairjs/minimal-gateway docker run -p 8888:8888 eclairjs/minimal-gateway
Now you can run any of the examples using the run.sh script from the examples directory, e.g.:
./run.sh --docker wordcount/wordcount.js
Please not that if you are running the docker container in a docker-machine environment or on another server, make sure you set the following environment variables:
export JUPYTER_HOST=<docker host ip, defaults to 127.0.0.1> export JUPYTER_PORT=<container ip, defaults to 8888>
Note: This repository supports Apache Spark 2.0, and it supercedes an set of repositories (EclairJS/eclairjs-node and EclairJS/eclairjs-nashorn) that supported an earlier version of Spark, namely 1.6. The focus of the EclairJS work going forward will be on supporting Spark 2.0.
