GH-27: add support for a share lib directory in HDFS for action binaries.
-------------------------------------------------------------------------
Key: OOZIE-73
URL: https://issues.apache.org/jira/browse/OOZIE-73
Project: Oozie
Issue Type: Bug
Reporter: Hadoop QA
Currently every workflow that uses a pig action must bundle the Pig JAR in the
workflow lib/ directory.
This is also true for commonly use JARs files across different workflow apps.
By adding a share lib job property, which is added as a secondary lib/
directory, all commons JARs (Pig, Hive) can be added in a /usr/share/lib
directory in HDFS and used by multiple workflow applications without having to
have a private copy per workflow app.
The location of HDFS share lib would be specified as job property (a later rev
of the workflow XML schema may add support for it too)
