-----------------------------------
Summary: Misc code cleanup
Key: OOZIE-2700
URL: https://issues.apache.org/jira/browse/OOZIE-2700
Project: Oozie
Issue Type: Sub-task
Reporter: Peter Bacsko
In the scope of OYA, we have the opportunity to increase the code quality of
Oozie.
The following things could be improved:
* Remove hard-coded, repeated strings and place them to static variables
* Eliminate unnecessary @SuppressWarnings annotations
* Proper usage of generics, eg. {{Class<?>}} instead of just {{Class}}
* Replace deprecated method calls to something else, for example:
** {{DistributedCache.addCacheFile()}}
** {{DistributedCache.createSymlink()}}
** {{SequenceFile.Reader()}} (two deprecated constructors)
* Remove unused imports
* In general, we should look for compile time warnings and take appropriate
actions to resolve them, if possible
Note that these changes are very small and don't require large testing efforts.
The list above is not exhaustive, so feel free to include ideas.
