Apache Oozie is a Java web application that is used with Apache Hadoop systems. In these big data systems, Apache Oozie is a kind of job handling tool that works in the general Hadoop environment with other individual tools like YARN as well as MapReduce and Pig.
Essentially, Apache Oozie bundles individual job tasks into logical work units. It allows for more sophisticated scheduling and job handling. One aspect of Apache Oozie is that engineers can assemble complex data processes that can make it easier to administrate Hadoop workflows.
Individual Apache Oozie tools include Oozie Workflow and Oozie Coordinator. Oozie Workflow helps look at bundles of tasks sequentially. Oozie Coordinator helps with scheduling.
Like other Apache products, Apache Oozie is offered under an Apache Foundation software license and is part of the Hadoop tool set that has community support as a type of open-source software system, rather than a proprietary, vendor-licensed system. Since Hadoop has become immensely popular for analytics and other kinds of enterprise computing, tools like Oozie are also commonly considered within enterprise IT as solutions for data handling projects.
