Key: HADOOP-7395
URL: https://issues.apache.org/jira/browse/HADOOP-7395
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 0.23.0
Reporter: Yan Jinshuang
Priority: Minor
Fix For: 0.20.3
When use the command "job -counter<job-id> <group-name> <counter-name> " with
wrong group-name or wrong counter-name(with correct job-id), the result is
always 0. It is better to show the user the detail, like "illegal group-name",
"illegal counter-name", etc.
