The 7.0 releases introduces major changes.
Starting at 7.0 the punch runs natively on Kubernetes. The official kubernetes distribution is the thales kast 1.2.0 release.
Java 11 or greater is now the required java runtime. The release is tested with openjdk64-22.214.171.124.
Spark and pyspark punchlines require a spark3 release. Spark standalone cluster is not supported on production environment, the punch only leverage the kubernetes spark mode.
Elasticsearch is only supported in the opendistro open source release. Elastic releases are not supported anymore.
Note also that the hadoop elasticsearch connectors have been deprecated as well. This means that the elasticsearch spark nodes and storm spout have both been removed. The punch still provide its own (hadoop elasticsearch free) implementations.
All configuration files are provided only using the yaml format. JSON and HJSON are only supported for backward compatibility. Make sure you progressively migrate to yaml files only.
The punch provides a tool
hjson-manager that automatically converts hjson or json to yaml:
cat some-file.hjson | hjson-manager --yaml
Plans can now run any kind of application:
planctl start \ --runtime user_defined \ --plan plan.hjson \ --template template.hjson \ --user-defined argument1 \ --user-defined argument2
- storm cluster: The storm cluster mode is deprecated. It is only supported for migration purpose. The storm single process mode is still supported, and has been renamed 'punch' as it is implemented on top of a proprietary punch engine.
- shiva : the shiva orchestrator is supported on the 7.0.0 but is marked for depreciation. It will be fully replaced by kubernetes starting at 8.0 and greater.
