Zhijie Shen commented on MAPREDUCE-5372:
----------------------------------------
In MAPREDUCE-5233, we intentionally changed ControlledJob#getMapredJobID to
ControlledJob#getMapredJobId, because we wanted to add Job#getMapredJobID,
which returns String, to be binary compatible to MR1. Therefore, it's already
impossible for ControlledJob in MR1 and RM2 to have the same method name. I'm
afraid changing getMapredJobId to another name doesn't help. In addition, this
is an incompatible change again, where we struggled a lot ago.
> ControlledJob#getMapredJobID capitalization is inconsistent between MR1 and
> MR2
