 # dnet-hadoop
-
-Dnet-hadoop is the project that defined all the [OOZIE workflows](https://oozie.apache.org/) for the OpenAIRE Graph construction, processing, provisioning.

-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.
