Redeploying the Oozie ShareLib
Some Oozie actions – specifically DistCp, Streaming, Pig, Sqoop, and Hive – require external JAR files in order to run. Instead of having to keep these JAR files in each workflow's lib folder, or forcing you to manually manage them using the oozie.libpath property on every workflow using one of these actions, Oozie provides the ShareLib. The ShareLib behaves very similarly to oozie.libpath, except that it’s specific to the aforementioned actions and their required JARs.
