What is work flow application consists of in Oozie

Question

Can anyone explain what is the work flow application in Oozie and how can we access Oozie from HDFS?

Answer 1

Hi,

A workflow application consists of the workflow definition and all the associated resources such as MapReduce Jar files, Pig scripts, etc. Applications need to follow a simple directory structure and are deployed to HDFS so that Oozie can access them.

An example directory structure is shown below:

<name of workflow>/</name>
??? lib/
? ??? hadoop-examples.jar
??? workflow.xml
