Description

With auto local mode, hadoop 2 getJob, getMapTaskReports, getReduceTaskReports api cause NumberFormatException with stack similar to following-
(I have also noticed that getMapTaskReports causes memory leak and OOMs for long running jobs as hadoop 2 map task reports are quite bulky, but that is a separate issue)
