Description

The Job Summary Appender (JSA) is introduced in 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 together with other M/R1 files. This appender is no longer used and I guess we can remove it.
