Prerequisitesīefore proceeding with this tutorial, you must have a conceptual understanding of Cron jobs and schedulers. For these details, Oozie documentation is the best place to visit. I'm trying to do task for oozie by web-constructor integrated in Hue. Oozie workflow: The Oozie workflow is the sequential set of actions that are to be executed. Oozie triggers workflow actions, which in turn use the Hadoop execution engine for actually executing the task. My need is the task for scheduler which send HQL-request to Hive. It supports all Hadoop jobs like Pig, Sqoop, Hive, and system-specific jobs such as Shell and Java. This tutorial is intended to make you comfortable in getting started with Oozie and does not detail each and every function available. There is a cluster with Cloudera including Hue. 3+ years of experience on BIG DATA using HADOOP framework and related technologies such as HDFS, HBASE, Map Reduce, HIVE, PIG, FLUME, OOZIE, SQOOP. This tutorial has been prepared for professionals working with Big Data Analytics and want to understand about scheduling complex Hadoop jobs using Apache Oozie. By the end of this tutorial, you will have enough understanding on scheduling and running Oozie jobs on Hadoop cluster in a distributed environment. This tutorial explores the fundamentals of Apache Oozie like workflow, coordinator, bundle and property file along with some examples. It is tightly integrated with Hadoop stack supporting various Hadoop jobs like Hive, Pig, Sqoop, as well as system specific jobs like Java and Shell. In addition, from this tab you can view the details of the Pig, Hive or Oozie activity as a whole, and compare it to similar activities. You should be able to run this on any Windows / Mac / Linux machine so long as you have enough disk space and RAM.

You can get the sandbox for VM-Ware (commercial - but there is a free viewer) or for VirtualBox (which is free).
This tutorial explains the scheduler system to run and manage Hadoop jobs called Apache Oozie. The Activity Children tab shows the same information as does the Activities tab, except that it shows only jobs that are children of a selected Pig, Hive or Oozie activity. This is a pre-installed single-node Hadoop cluster inside a virtual machine. Oozie also provides a mechanism to run the job at a given schedule.
