OOZIE-135: support multiple shared lib path in oozie
----------------------------------------------------
Key: OOZIE-552
URL: https://issues.apache.org/jira/browse/OOZIE-552
Project: Oozie
Issue Type: New Feature
Reporter: Hadoop QA
Assignee: Roman Shaposhnik
It would be great if oozie.libpath can take more than one path. That would help
to modularize the shared library directory. A user specifies all shared library
paths used by the workflow and Oozie combines the resources into one.
For example, my wf contains 2 actions - one pig action + one hive action.
I can have:
libpath=/user/share/pig-0.7,/user/share/hive-0.6.
Otherwise, I have to put everything into one single huge /user/share/common/,
which can become cumbersome.
Note: the shared library path (either a single path or multiple paths) is to
allow somebody to sanitize all share dependencies and then easily use them
without conflicts, so it needs to be checked carefully before use to ensure
there is no class or any other conflicts.
