Hop Conf - The Hop command line configuration tool
Usage
Hop Conf is a command line tool to manage environments. The hop-conf.sh script can be run with the -h flag (./hop-conf.sh -h) to display available options.

Running Workflows and Pipelines
You can specify an environment or a project when executing a pipeline or a workflow. By doing so you are automatically configuring metadata, variables without too much fuss.
The easiest example is shown by executing the "complex" pipeline from the Apache Beam examples:
-
Windows
-
Linux, macOS
hop-run.bat --project samples --file 'beam/pipelines/complex.hpl' --runconfig DirectExpected output:
C:\<YOUR_PATH>\hop>echo off

-DHOP_PLATFORM_RUNTIME=Run -DHOP_AUTO_CREATE_CONFIG=Y
Consolidated parameters to pass to HopRun are
--project samples --file beam/pipelines/complex.hpl --runconfig Direct
Command to start HopRun will be:

2022/12/16 14:27:42 - General - Executing this pipeline using the Beam Pipeline Engine with run configuration 'Direct'To execute an Apache Beam pipeline a lot of information and metadata is needed. Let’s dive into a few fun information tidbits:
-
By referencing the
samplesconfig/projects/samples -
Since we know the location of the project, we can specify pipelines and workflows with a relative path
-
The project knows where its metadata is stored (
config/projects/samples/metadataDirectconfig/projects/samples/metadata/pipeline-run-configuration/Direct.json -
This run configuration defines its own pipeline engine specific variables, in this case the output folder :
DATA_OUTPUT=${PROJECT_HOME}/beam/output/ -
The output of the samples is as such written to
config/projects/samples/beam/output
To reference an environment you can execute using -e--environment
Cloud Storage Configuration
Hop Conf can be used to configure your AWS, Azure and Google Cloud (Cloud Storage and Drive) accounts with Hop through VFS
