GH-106: add support for an (Oozie) system share lib directory in HDFS for
action binaries.
------------------------------------------------------------------------------------------
Key: OOZIE-133
URL: https://issues.apache.org/jira/browse/OOZIE-133
Project: Oozie
Issue Type: Bug
Reporter: Hadoop QA
This issue builds on top of GH-0027
The motivation for GH-0027 is to allow workflow apps to easily share a common
set of JAR/SO libraries without having to bundle those JAR/SO libs in each
workflow app lib/ directory.
The motivation for this issue is to allow the (Oozie) system to use set a
default set of JAR/OS libraries in the workflow application path. A useful
feature when a setup is defining a common stack (i.e. for pig, streaming, hive,
sqoop, inputformats, UDFs libs, etc) and a workflow app just want to use the
stack.
To maintain backward compatibility, by default this system defined 'share lib'
directory is not included. Workflow jobs must set a flag in their job
properties for the inclusion to happen.
A future version of workflow apps would revert the default behavior.
