> Users often complain about the XML they have to write for Oozie jobs. It
> would be nice if they could write them in something like Java, but we don't
> want to have to maintain a separate Java API for this. I was looking around
> and saw that JAXB might be the right thing here. From what I can tell, it
> lets you create Java classes from XSD schemas. So, we should be able to
> auto-generate a Java API for writing Oozie jobs, without having to really
> maintain it.
> We should investigate if this is feasible and, if so, implement it.
> Some useful looking links:
> * [JAXB
> overview|https://en.wikipedia.org/wiki/Java_Architecture_for_XML_Binding]
> * [JAXB description|https://jaxb.java.net/2.2.11/docs/ch03.html]
> * [Maven JAXB plugin|https://java.net/projects/maven-jaxb2-plugin/pages/Home]
> * [Apache Falcon|https://falcon.apache.org]
> Key features:
> * must have:
> ** inside a {{fluent-job-api}} artifact
> ** able to create workflow / coordinator / bundle definitions programmatically
> ** synchronizing each and every XSD change on rebuild
> ** can write {{workflow.xml}}, {{coordinator.xml}}, {{bundle.xml}}, and
> {{jobs.properties}} artifacts of every XSD version
> ** cloneability of workflow etc. {{Object}} s
> ** perform cross checks, e.g. that the workflow graph is a DAG
> ** only latest XSD versions should be supported as must have
> * nice to have:
> ** XSD version(s) can be provided. When not provided, latest ones are
> considered as valid
> ** implement a [*fluent API*|https://en.wikipedia.org/wiki/Fluent_interface]
> ** have a Python / Jython / Py4J REPL to make it easy to experiment with also
> for data engineers / data scientists
> ** create documentation about usage
> ** can read {{workflow.xml}}, {{coordinator.xml}}, {{bundle.xml}}, and
> {{jobs.properties}} artifacts of every XSD version
> ** can convert between XSD versions
> ** support XSD change on the fly (within REPL)
> ** support HDFS reads / writes
> ** support dry run on an Oozie server to perform checks
