## Our Standards
Examples of behavior that contributes to creating a positive environment include:
- Using welcoming and inclusive language
- Being respectful of differing viewpoints and experiences
- Gracefully accepting constructive criticism
- Attempting collaboration before conflict
- Focusing on what is best for the community
- Showing empathy towards other community members
Examples of unacceptable behavior by participants include:

- Other conduct which could reasonably be considered inappropriate in a professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org/), [version 1.4](https://www.contributor-covenant.org/version/1/4/code-of-conduct.html).

# dnet-hadoop # dnet-hadoop
Dnet-hadoop is the project that defined all the OOZIE workflows for the OpenAIRE Graph construction, processing, provisioning.
Dnet-hadoop is the project that defined all the [OOZIE workflows](https://oozie.apache.org/) for the OpenAIRE Graph construction, processing, provisioning.
This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
By participating, you are expected to uphold this code. Please report unacceptable behavior to [dnet-team@isti.cnr.it](mailto:dnet-team@isti.cnr.it).
This project is licensed under the [AGPL v3 or later version](#LICENSE.md).
How to build, package and run oozie workflows
====================
Oozie-installer is a utility allowing building, uploading and running oozie workflows. In practice, it creates a `*.tar.gz`
package that contains resources that define a workflow and some helper scripts.
This module is automatically executed when running:
`mvn package -Poozie-package -Dworkflow.source.dir=classpath/to/parent/directory/of/oozie_app`
on module having set:
```
<parent>
<groupId>eu.dnetlib.dhp</groupId>
<artifactId>dhp-workflows</artifactId>
</parent>
```
in `pom.xml` file. `oozie-package` profile initializes oozie workflow packaging, `workflow.source.dir` property points to
a workflow (notice: this is not a relative path but a classpath to directory usually holding `oozie_app` subdirectory).
The outcome of this packaging is `oozie-package.tar.gz` file containing inside all the resources required to run Oozie workflow:
- jar packages
- workflow definitions
- job properties
- maintenance scripts
Required properties
====================
In order to include proper workflow within package, `workflow.source.dir` property has to be set. It could be provided
by setting `-Dworkflow.source.dir=some/job/dir` maven parameter.
In oder to define full set of cluster environment properties one should create `~/.dhp/application.properties` file with
the following properties:
- `dhp.hadoop.frontend.user.name` - your user name on hadoop cluster and frontend machine
- `dhp.hadoop.frontend.host.name` - frontend host name
- `dhp.hadoop.frontend.temp.dir` - frontend directory for temporary files
- `dhp.hadoop.frontend.port.ssh` - frontend machine ssh port
- `oozieServiceLoc` - oozie service location required by run_workflow.sh script executing oozie job
- `nameNode` - name node address
- `jobTracker` - job tracker address
- `oozie.execution.log.file.location` - location of file that will be created when executing oozie job, it contains output
produced by `run_workflow.sh` script (needed to obtain oozie job id)
- `maven.executable` - mvn command location, requires parameterization due to a different setup of CI cluster
- `sparkDriverMemory` - amount of memory assigned to spark jobs driver
- `sparkExecutorMemory` - amount of memory assigned to spark jobs executors
- `sparkExecutorCores` - number of cores assigned to spark jobs executors
All values will be overriden with the ones from `job.properties` and eventually `job-override.properties` stored in module's
main folder.
When overriding properties from `job.properties`, `job-override.properties` file can be created in main module directory
(the one containing `pom.xml` file) and define all new properties which will override existing properties.
One can provide those properties one by one as command line `-D` arguments.
Properties overriding order is the following:
1. `pom.xml` defined properties (located in the project root dir)
2. `~/.dhp/application.properties` defined properties
3. `${workflow.source.dir}/job.properties`
4. `job-override.properties` (located in the project root dir)
5. `maven -Dparam=value`
where the maven `-Dparam` property is overriding all the other ones.
Workflow definition requirements
====================
`workflow.source.dir` property should point to the following directory structure:
[${workflow.source.dir}]
|
|-job.properties (optional)
|
\-[oozie_app]
|
\-workflow.xml
This property can be set using maven `-D` switch.
`[oozie_app]` is the default directory name however it can be set to any value as soon as `oozieAppDir` property is
provided with directory name as value.
Sub-workflows are supported as well and sub-workflow directories should be nested within `[oozie_app]` directory.
Creating oozie installer step-by-step
=====================================
Automated oozie-installer steps are the following:
1. creating jar packages: `*.jar` and `*tests.jar` along with copying all dependencies in `target/dependencies`
2. reading properties from maven, `~/.dhp/application.properties`, `job.properties`, `job-override.properties`
3. invoking priming mechanism linking resources from import.txt file (currently resolving subworkflow resources)
4. assembling shell scripts for preparing Hadoop filesystem, uploading Oozie application and starting workflow
5. copying whole `${workflow.source.dir}` content to `target/${oozie.package.file.name}`
6. generating updated `job.properties` file in `target/${oozie.package.file.name}` based on maven,
`~/.dhp/application.properties`, `job.properties` and `job-override.properties`
7. creating `lib` directory (or multiple directories for sub-workflows for each nested directory) and copying jar packages
created at step (1) to each one of them
8. bundling whole `${oozie.package.file.name}` directory into single tar.gz package
Uploading oozie package and running workflow on cluster
=======================================================
In order to simplify deployment and execution process two dedicated profiles were introduced:
- `deploy`
- `run`
to be used along with `oozie-package` profile e.g. by providing `-Poozie-package,deploy,run` maven parameters.
The `deploy` profile supplements packaging process with:
1) uploading oozie-package via scp to `/home/${user.name}/oozie-packages` directory on `${dhp.hadoop.frontend.host.name}` machine
2) extracting uploaded package
3) uploading oozie content to hadoop cluster HDFS location defined in `oozie.wf.application.path` property (generated dynamically by maven build process, based on `${dhp.hadoop.frontend.user.name}` and `workflow.source.dir` properties)
The `run` profile introduces:
1) executing oozie application uploaded to HDFS cluster using `deploy` command. Triggers `run_workflow.sh` script providing runtime properties defined in `job.properties` file.
Notice: ssh access to frontend machine has to be configured on system level and it is preferable to set key-based authentication in order to simplify remote operations.
