Chen Zhi created HADOOP-16162:
---------------------------------

             Summary: Remove unused Job Summary Appender configurations from log4j.properties
                 Key: HADOOP-16162
                 URL: https://issues.apache.org/jira/browse/HADOOP-16162
             Project: Hadoop Common
          Issue Type: Improvement
          Components: conf
    Affects Versions: 2.0.3-alpha
            Reporter: Chen Zhi
         Attachments: diff

The Job Summary Appender (JSA) is introduced in [MAPREDUCE-740|https://issues.apache.org/jira/browse/MAPREDUCE-740] to provide the summary information of the job's runtime. And this appender is only referenced by the logger defined in org.apache.hadoop.mapred.JobInProgress$JobSummary. However, this class has been removed in [MAPREDUCE-4266|https://issues.apache.org/jira/browse/MAPREDUCE-4266] together with other M/R1 files. This appender is no longer used and I guess we can remove it.
