- HDFS security token support
- "ship/" directory to transfer files to all TaskManagers (user-files)
- Log4j-based logging (YARN now respects the logging configuration)
- the YARN-client deletes all "temp" files from HDFS.
- The JVMs started by YARN now respect the configured JVM opts in the yaml-file
- the JobManager webinterface shows the log file (e.g it is aware of the YARN-specific log-directory)
- The YARN-client now creates a hidden ".yarn-jobmanager" with the address of the JobManager in YARN. users do not have to specify the -m argument anymore.
- Fix a little bug with the JobManager's "cloud" model for taskManager with less that 1GB memory.

- Tested on Cloduera Hadoop 5 Beta 2 WITH CDH5-B2 Maven Dependencies.
