> 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.
