[jira] Created: (MAPREDUCE-994) bin/hadoop job -counter help
options do not give information on permissible values.
bin/hadoop job -counter help options do not give information on permissible values.
-----------------------------------------------------------------------------------
Key: MAPREDUCE-994
URL: https://issues.apache.org/jira/browse/MAPREDUCE-994
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Iyappan Srinivasan
Priority: Minor
Right now, bin/hadoop job -counter gives this output
bin/hadoop job -counter
DEPRECATED: Use of this script to execute mapred command is deprecated.
Instead use the mapred command for it.
Usage: CLI [-counter <job-id> <group-name> <counter-name>]
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.
Group_name Ex:
org.apache.hadoop.mapreduce.TaskCounter
Counter name example:
REDUCE_INPUT_RECORDS

[jira] Commented: (MAPREDUCE-994) bin/hadoop job -counter help

Meng Mao commented on MAPREDUCE-994:
------------------------------------
I agree, though currently the usage output is simply:
$ hadoop job -counter
Usage: JobClient [-counter <job-id> <group-name> <counter-name>]
I couldn't the example of
hadoop job -counter org.apache.hadoop.mapreduce.TaskCounter REDUCE_INPUT_RECORDS
to work. Is it working for others? Access to the various MapReduce counters would be highly desirable.
