> The property mapreduce.job.counters.limit was introduced in MAPREDUCE-1943, but the mechanism
was changed in MAPREDUCE-901 where the property name was changed to mapreduce.job.counters.max
without supporting the old name. We should deprecate but honour the old name to make it easier
for folks to move from Hadoop 1 to Hadoop 2.
