How to spray data without using the ECL IDE?

Comments and questions related to the Enterprise Control Language

I want to spray data files to Thor inside of ECL program. I know, with the IDE, I need to load files into the landing zone first and then spray the file into Thor from there. But, How can do this with ECL program or external scripts outside of the IDE?

A more general question is how to run ECL programs without using the IDE.

Any help is appreciated.

There are three ways to spray/despray files and keys:

1. DFU command line:
DFUPLUS.exe takes command line parameters which are sent to DFU via ESP server.
A number of options are available for you to control how the spray is done.

2. ECL Watch:
Proprietary GUI web application which is used for monitoring the LN HPCC components and query activity.
Logical files are listed for available Landing Zones.
Available clusters are shown.
Spraying is done by completing a form supplying the information required.
You can check the progress of a spray/despray and confirm its success or failure.

3. Programmatically, using file services:
Spraying can be controlled from within the ECL code.
This method is often used when automating regular production jobs.
See the EclLibrary in the ECL IDE Repository for more details.

You can always execute ECL code from the command line using ECL Plus.
