Oozie – Oozie, Workflow Engine for Apache Hadoop - Apache Oozie

IntroductionBig data is crucial toata analytics and learning help corporations foresee client demands, provide usommendations, an. To overcome this, Yahoo developed Oozie, a founaging multi-step processes in MapReduce, Pig, etc.Source: oreilley.comLearning ObjectivesUnderstand what it is apache oozie and what are its typesWe are going to learn how it worksWhat is a workflow engine?This article was published as a part of the Data Science Blogathon.Table of ContentsWhat is Apache Oozie?Types of Oozie JobsFeatures of OozieHow does Oozie work?Deployment of Workflow ApplicationWrapping upWhat is Apache Oozie?What is Apache Oozie?Apache Oozie is a workflow scheduler system fessive way to carry out a larger job. Two or more duties in a job sequence can also be programmed to operate concurrently. It is basically an Open-Source Java Web Application licensed under the Apache 2.0 license. It is in charge of initiating workflow operations, which are then processed by tAs a result, Oozie may use the current Hadoop infrastructure for load balancing, fail-over, and so on.It can be used to quickly schedule MapReduce, Sqoop, Pig, or Hive tasks. Many different types of jobs can be integrated using Apache oozie, and a job pipeline of one’s choice can be quickly established.Types of Oozie JobsOozie Workflow Jobs: Apache Oozie workflow is a set of action and control nodes organized in a DAG. DAG is a directed acyclic graph (DAG) that captures control dependency, with each action representing a Hadoop job, Pig, Hive, Sqoop, or Hadoop DistCp job. Aside from Hadoop tasks, there are other operations like Java apps, shell scripts, and email Oozie Coordinator Jobs: To resolve trigger-based workflow computation, the Apache Oozie coordinator is employed. It provides a foundation for providing triggers or predictions, after which it schedules the workflow depending on those established triggers. It allows officials to monitor and regulate workflow processes in response to group conditions and application-specific constraints.Oozie Bundle: It is a group of Oozie coordinator apps that give instructions on when to launch that coordinator. Users can start, stop, resume, suspend, and rerun at the bundle level, giving them complete control. Bundles are also defined using an XML-based language called the Bundle

Application that adheres to this pattern.The command for copying files to HDFS% hadoop fs -put hadoop-examples/target/ name of workflowRun Oozie Workflow JobTo run the jobs, we’ll need to use the Oozie command-line tool, which is an important client program that talks to the Oozie server.Step 1: Export the OOZIE URL environment variable to define the Oozie command that sets the Oozie server to use for processing.% export OOZIE_URL=" 2: Use the -config option to run the Oozie workflow Job, which refers to a local Java properties file. The file includes definitions for the parameters used in the workflow XML file.% oozie job -config ch05/src/main/resources/max-temp-workflow.properties -runStep 3: The oozie.wf.application.path. It informs the Oozie of the location of the workflow application in HDFS.nameNode=hdfs://localhost:8020jobTracker=localhost:8021oozie.wf.application.path=${nameNode}/user/${user.name}/Step 4: The status of a workflow job can be determined by using the subcommand ‘job’ with the ‘-info’ option, which requires giving the job id after ‘-info’, as explained below. Depending on job status, RUNNING, KILLED, or SUCCEED will be shown. % oozie job -infoStep 5: To receive the result of successful workflow computation, we must run the following Hadoop command. % hadoop fs -catConclusionWe learn how to deploy workflow apps and operate the workflow application. It initiates work process operations using the Hadoop processing engine to carry out several tasks. It uses modern Hadoop hardware for load balancing, failover, etc. Oozie is responsible for determining the completion of tasks through callbacks and polling. Insights from the article:We Apache Oozie schedule Hadoop jobs in a scattered environment.A workflow engine stores and runs Hadoop workflows like MapReduce, Pig, etc.Control-flow nodes provide conditional logic to facilitate process coordination.Java apps may use the Oozie command line interface and client API to manage and keep tabs on processes.We hope you liked this post; please share your thoughts in the comments below.The media shown in this article is not owned by Analytics Vidhya and is used at the Author’s discretion.

It requires is not available. The alarm text includes specific information about the problem. AutoSys Workload Automation attempts to restart the job after a suitable delay.Indicates that the manually generated sendevent -E RESTARTJOB command fails, typically due to one of the following reasons:The job is not in a FAILURE state.The job is not an SAP BW Process Chain, Microfocus, or Informatica job.AutoSys Workload Automation displays RESTARTJOBFAIL alarms when you create a report using the autorep -J -d command.Indicates that the RESUMEJOB event fails; typically when you send the event when the Hadoop Oozie workflow is not in the SUSPENDED state.RETURN_RESOURCE_FAIL (543)Indicates that the resource manager cannot return a resource.Indicates that the SEND_SIGNAL event fails.SERVICEDESK_FAILURE (533)Indicates that the scheduler cannot open a CA Service Desk ticket for the failing job.Indicates that AutoSys Workload Automation cannot start a job, typically due to communication problems with the remote machine. AutoSys Workload Automation attempts to restart the job.Indicates that the SUSPENDJOB event fails; typically when you send the event when the Hadoop Oozie workflow is not in the RUNNING state.Indicates that Telemetry failed to collect or send data.Indicates that the scheduler cannot send a notification for the requesting job to the Notification Services component of CA NSM.Indicates that the version number that the calling routine generates and the version number of the agent do not match. Inspect the agent log file, and install the proper agent version.Indicates that a job cannot continue running until it receives a user reply.

Specification Language. It is a very useful degree of abstraction in many major corporations.It is indeed quite flexible. Jobs can be begun, paused, interrupted, and restarted with ease. Rerunning failed workflows is a breeze with Oozie.Features of OozieJobs can be controlled from anywhere using its Web Service APIs.It contains a client API amand-line interface that can be used from a Java application to initiate, control, and monitor jobs.It provides the ability to perform jobs that are scheduled to run regularly.It has the ab send email reminders when jobs are completed.How does Oozie work?It is a service that runs in the Hadoop group and on client computers. It sends workflow definitions for immediate or delayed processing. The workflow is mainly made up of action and control-flow nodes.An action node represents a workflow job, like transferring files into HDFS, running MapReduce, Pig, or Hive jobs, importing data with Sqoop, or processing a shell script of a Java program.A control-flow node manages the workflow processing between actions by allowing features like conditional logic, which allows alternative branches to be followed based on the outcome of a former action node.Source: oreilly.comThis group of nodes includes the Start Node, End Node, and Error Node.The Start Node indicates the beginning of the workflow job.The End Node indicates the end of the job.The Error Node denotes the existence of an error and the associated error message to be written.It uses an HTTP callback at the end of a workflow process to notify the client of the workflow status. The callback may be caused by entering or exiting an action node too.Deployment of Workflow ApplicationThe workflow description and each connected resource, like Pig scripts, MapReduce Jar files, and so forth, make up a workflow application. The workflow application must adhere to a simple directory structure deployed to HDFS so that it can access it.Directory Structure/??? lib/? ??? hadoop-application-examples.jar??? workflow.xmlWorkflow.xml (a workflow definition file) must be kept in the top-level directory (parent directory). Jar files containing MapReduce classes can be found under the Lib directory. Any build tool, like Ant or Maven, can be used to create a workflow
