[jira] [Created] (OOZIE-1254) Use NDC or MDC for logging

Rohini Palaniswamy created OOZIE-1254:
-----------------------------------------

             Summary: Use NDC or MDC for logging
                 Key: OOZIE-1254
                 URL: https://issues.apache.org/jira/browse/OOZIE-1254
             Project: Oozie
          Issue Type: Improvement
            Reporter: Rohini Palaniswamy


 Because of the XLog prefix design to log USER[-] GROUP[-] TOKEN[-] APP[-] JOB[-] ACTION[-], issues like OOZIE-1251 crop up when some one declares XLog unintentionally as a static class variable. Even if non-static variable, it might have issues if multiple threads access the same object. Also it is inefficient as we have to create a XLog object for each instance instead of making it static.

  NDC and MDC in log4j have been designed for this specific purpose. We should be using one of them.
