Right now,  bin/hadoop job -counter  gives this output

DEPRECATED: Use of this script to execute mapred command is deprecated.
Instead use the mapred command for it.

What are these group names and what are the counter-names is not explained. All permissible values of group-name> and <counter-name> should be specified.

org.apache.hadoop.mapreduce.TaskCounter 

Counter name example:
REDUCE_INPUT_RECORDS
