Hi All, When I was working on stabilizing Avro RPC versions of file manager, workflow manager and resource manager, it became extremely difficult to debug due to lack of logging in OODT. Therefore, we need more logging support throughout the project. Personally, I find *java.util.Logging (JUL)* not convenient to use since it requires explicit string concatenation when logging.
As a solution, I suggest to use SLF4J which has already been used partially in same components in OODT. Therefore, I have re-opened an existing issue [1] related to this and created few sub tasks. I want to know your opinion on following, 1. As for now, we can redirect [2] JUL logs to SLF4J logs by adding a new handler to existing logging.properties files. Will that be ok? In future we can completely remove JUL log lines. 2. Will there be any backward compatibility issue if we add log4j2 along with log4j2.xml's to distributions from 1.9 onwards? What are your thoughts?
