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. > 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 -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
