    [ https://issues.apache.org/jira/browse/HADOOP-4039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12627616#action_12627616 ] 

Vinod Kumar Vavilapalli commented on HADOOP-4039:
-------------------------------------------------

This list might get long depending upon how long job-status information is persisted in DFS, which is given by the value of mapred.job.tracker.persist.jobstatus.hours specified in hours. So, in similar lines, we can have a "-n NoOfHours" option to -list option, defaulting it to 24 hours.

> After {{mapred.jobtracker.retirejob.interval}} elapses, completed jobs are no longer maintained by the JT, but instead when job-client ask for job status, counters or task completion events, the relevant information is picked up from completed job store. But a retired job is not listed in the output of "{{hadoop job -list all}}", without which other information from completed job store isn't quite useful unless a job-id is known from elsewhere.
