Description

As the default configuration file shows,
https://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/mapred-default.xml

we can configure options
mapreduce.map.skip.proc.count.autoincr
mapreduce.reduce.skip.proc.count.autoincr
in the mapred-default.xml. But they do not work because the expected keys in org.apache.hadoop.mapreduce.MRJobConfig.java

public static final String MAP_SKIP_INCR_PROC_COUNT = "mapreduce.map.skip.proc-count.auto-incr"
public static final String REDUCE_SKIP_INCR_PROC_COUNT = "mapreduce.reduce.skip.proc-count.auto-incr";

Or
in org.apache.hadoop.mapreduce.util.ConfigUtil.java

new DeprecationDelta("mapred.skip.map.auto.incr.proc.count",
MRJobConfig.MAP_SKIP_INCR_PROC_COUNT),
new DeprecationDelta("mapred.skip.reduce.auto.incr.proc.count",
MRJobConfig.REDUCE_SKIP_INCR_PROC_COUNT),

we can change them to mapreduce.map.skip.proc-count.auto-incr and mapreduce.reduce.skip.proc-count.auto-incr in the default configuration file.
