So you've installed the HPCC Systems platform, Client Tools and ECL IDE (or an editor of your choice):
Certify your system is functioning correctly
- Preflight - Open ECL Watch and navigate to the Operations area to run a preflight check on all Systems Servers and Cluster Processes to make sure all machines are running and operating as expected with available disk space, memory and CPU. Failed components or results falling outside the expected norm are shown in orange. Find out more using our Preflight and Certification Guide or Using ECL Watch Guide.
- _Certification - Check that your Thor and Roxie components are working correctly and giving results as expected. This example is located in your C:\Users\Public\Documents\HPCC Systems\ECL\My Files\Examples folder, however ECL IDE (or the editor you are using) will display the available files in your repository tree. Take a look at ReadMeFirst.ecl to make sure you are set up correctly and to find out the sequence you should use to run the files in the correct order. More information about running our _Certifcation script is available in our Preflight and Certification Guide.
Follow the examples in our installation guide to run some simple programs
- Run a basic 'Hello World' program both from the command line and using an editor, such as our ECL IDE.
- Run a simple anagram query on Thor.
- Spray a word list file to Thor and run a second anagram query using this file to evaluate which results are actual words. Publishing the query to Roxie allows you to use a web based interface (Ws-ECL) to enter a word from which to make anagrams using this query.
Work through a tutorial to see HPCC Systems in action
Get your data on and off HPCC Systems. Find out how to spray (import) and despray (export) your data from your HPCC Systems landing zone. Learn how to copy data from one cluster to another and also how to replicate data held on a cluster in one HPCC Systems environment, on a cluster in a completely different HPCC Systems environment.
|Work through the query development process from beginning to end. See how ECL is used to process and query the data supplied which includes names and addresses. This tutorial also serves as an introduction to our Data Refinery Cluster (Thor) and our Data Delivery Engine (Roxie).
|ECL Programmers Guide
|Try out some ECL language features. Download our example code and use your chosen development environment (for example our ECL IDE) to see how a sample of the most commonly used ECL language features work. Learn about ECL programming concepts, working with super files, using Roxie and embedded languages and datastores.
|ECL Best Practices
|Tips, tricks and best practices for coding in ECL. Learn about syntax, including naming conventions, indentation and how to avoid syntax errors cause by 'lost parentheses'. Find out why SET definitions are more practical than multiple OR conditions and learn how to translate your ECL idea into ECL code. Our Developer Forum Tips and Tricks area is also a great place to find out about other ways our users have found to solve their challenges use ECL.
|Six Degrees of Kevin Bacon
|Find out how many degrees of separation there are between Kevin Bacon and any actor included in the Internet Movie Database (IMDB), which you must download from this external data source. As well as demonstrating the processing power of HPCC Systems, this example perfectly illustrates how to extract links and find relationships in large quantities of data.
