Review request for oozie, András Piros, Peter Cseh, Peter Bacsko, and Robert 
Kanter.


Repository: oozie-git


Description
-------

Embedding jetty into Oozie so that it can run as a standalone application. The 
changes also try to address OOZIE-2317 (i.e. Tomcat 6 is EOL).

New functionality
- New module (server) is added that sets up an embedded Jetty server and start 
Oozie services. Servlet mapping is done by reading web.xml of webapp at 
runtime. JSP is handled with custom code. Server version is not revealed in 
server repsonses.
- SSL protocols and ciphers can be configured via system properties and 
environment variables. Precedence: system properties, environment variables, 
default values
   
Changes in existing code
- Excluded jetty 6 dependencies from core and updated tests accordingly  

Packaging
- oozie.sh is modified so that it starts Oozie with embedded jetty by default. 
If someone would like to use tomcat for any reason, they can set an environment 
variable (e.g. OOZIE_USE_TOMCAT=1).

TODO:
- Add more tests
- Add more documentation
- Code cleanup + refactoring in packaging and core parts
- Maven clean up
- Allow to tune more Jetty settings (for example threadpool)
- More security measures (e.g. protect against clickjacking, CSRF, etc.)
- Update Oozie Documentation

Testing
-------

- Tested basic functionality by executing a workflow that uses the sample 
JavaAction
    - without SSL - on a 2.4.0 pseudo Hadoop cluster
    - SSL with Kerberos is using a test CDH cluster 
- Added new unit tests that check
    - If oozie.ssl.enabled is not specified, server starts without SSL settings 
    - If oozie.ssl.enabled is specified, server starts with SSL settings
    - SSL protocols and ciphers can be configured via system properties and 
environment variables 
- Ran subset of tests using Hadoop-2 profile
    - mvn clean package assembly:single   -DjavaVersion=1.8 -DtargetVersion=1.7 
 -Dtest=TestJavaActionExecutor  -Phadoop-2 -Dhadoop.version=2.4.0


Thanks,
