QUESTION
According to the document of Oozie, I try to run a map-reduce example on Oozie. As everyone knows, 'workflow.xml' (and 'coordinator.xml') should be in HDFS.
Then input the command: oozie job -oozie http://localhost:11000/oozie -config examples/apps/map-reduce/job.properties -run
. And I also know the 'job.properties' should be in local file system.
But there are two things confused me:
1.why dose the jar or class variable in workflow.xml come from directory Lib of HDFS?
2.There is a picture showing the content of oozie-examples-4.3.1.jar. This jar is in HDFS, how can it import Lib?
Forgive my poor English.
...ANSWER
Answered 2018-Aug-22 at 03:46The highlighted red box is part of the Hadoop and Java default classpath. Any Java code that's ran within YARN, as part of MapReduce has access to the packages that appear when you run hadoop classpath
command. By the way, mapred.*
classes of Hadoop are almost all deprecated
That's nothing to do with Oozie, per say, but Oozie extends the Hadoop classpath with the Oozie ShareLib, which must be explicitly enabled with a property file argument

Install oozie-examples
You can use oozie-examples like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the oozie-examples component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
