Hop Tools

Hop contains a number of tools that are optimized for the various tasks Hop developers and administrators need to perform.

Hop GUI

Hop Gui is the visual IDE where Hop data developers create, test, run and manage the life cycle for workflows and pipelines. In addition to functionality for development and life cycle management, Hop Gui contains tools and perspectives to manage projects and environments, to search and manage metadata, to manage and version control a large variety of files and to explore logging in a Neo4j graph.

Hop Gui is designed to be platform independent.
Hop Web is a version of Hop Gui that works on browsers and mobile devices.

The command below starts Hop GUI for your operating system.

 

hop-gui.bat
bash

Expected output: Hop Gui starts.

Hop Conf

Hop Conf is a command line tool to manage various aspects of your Hop configuration: projects, environments, cloud configuration and more

The example hop-conf command below lists your available projects.

 

hop-conf.bat -pl
bash

Expected output:

C:\Program Files\Microsoft\jdk-11.0.17.8-hotspot\\bin\java" -classpath lib\core\*;lib\beam\*;lib\swt\win64\* -Djava.library.path=lib\core;lib\beam -Xmx2048m -DHOP_AUDIT_FOLDER=.\audit -DHOP_PLATFORM_OS=Windows -DHOP_PLATFORM_RUNTIME=Conf -DHOP_AUTO_CREATE_CONFIG=Y org.apache.hop.config.HopConfig  -pl

    Parent project: default
    Configuration file: file:\C:\<YOUR_PATH>\hop\config\projects\samples\project-config.json
shell

See the Hop Tools → Hop Conf documentation for more information.

Hop Encrypt

Hop Encrypt is a command line tool that obfuscates or encrypts a plain text password for use in XML, password or metadata files. Make sure to also copy the password encryption prefix to indicate the obfuscated nature of the password. Hop will then be able to make the distinction between regular plain text passwords and obfuscated ones.

 

The example below prints the encrypted Hop password mypassword.

 

hop-encrypt.bat -hop mypassword
bash

Expected output:

===[Environment Settings - hop-encrypt.bat]====================================

The example below runs the switch-case-basic.hpl pipeline in the samples project (-j) with the local native pipeline run configuration (-r).

 

hop-run.bat -r local -j samples -f ${PROJECT_HOME}/transforms/switch-case-basic.hpl

Hop Import

Hop Import is a command line tool to import PDI/Kettle jobs and transformations into Apache Hop.

Hop Import does a lot more than just a code conversion from jobs to workflows and transformations to pipelines: database connections are converted to Apache Hop rdbms connections, variables are parsed and imported, and everything is bundled into a full Apache Hop project.

 

The example command below prints the hop-import help. Check the Import Kettle (PDI) Projects in Apache Hop docs for more information.

 

hop-import.bat
