The attached patch implements the changes proposed above. During the process, we also fixed
a few minor issues:
- Changed the usage of java io API (File etc) to hadoop Path, FileSystem, Configuration.
- Upgraded the tests to junit 4.
- Use the newly added JsonObjectMapperParser to replace customized json parsing in TestRumenJobTraces.
- Replaced the usage of Vector to List in unit tests.
- Fixed an NPE bug in HadoopLogAnalyzer.
- Added an API getOutcome() in JobStory.
- Fixed a bug in ParsedHost where it fails to parse rack names contain non-digital characters.
- Fixed a bug where ZombieJob.getTaskInfo() returns uninitialized TaskInfo objects.
- Adapt the usage of newly added ClusterStory in ZombieJob.
