Subject [jira] Created: (MAPREDUCE-2381) JobTracker instrumentation not consistent about error handling
Date Mon, 14 Mar 2011 01:57:29 GMT
JobTracker instrumentation not consistent about error handling
--------------------------------------------------------------

                 Key: MAPREDUCE-2381
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2381
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Philip Zeyliger
         Attachments: MAPREDUCE-2381.patch.txt

In the current code, if the class specified by the JobTracker instrumentation config property
is not there, the JobTracker fails to start with a ClassNotFound.  If it's there, but it can't
load for whatever reason, the JobTracker continues with the default.  Having two different
error-handling routes is a bit confusing; I propose to move one line so that it's consistent.
 (On the TaskTracker instrumentation side, if any of the multiple instrumentations aren't
available, the default is used.)

The attached patch merely moves a line inside of the try block that's already there.
