User Log Retention across TT restarts

        Details

        • Type: Improvement
        • Status: Reopened
        • Priority: Minor
        • Resolution: Unresolved
        • Affects Version/s: 0.22.0

          Description

          The tasktrackers cleanup the userlog directory when they restart.
          This happens independent of value of mapred.userlog.retain.hours.

          The feature is to add a configurable feature to respect mapred.userlog.retain.hours across TT restarts
