[jira] [Commented] (MAPREDUCE-4149) Rumen fails to parse certain counter strings

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4149?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13253264#comment-13253264 ] 

Amar Kamat commented on MAPREDUCE-4149:
---------------------------------------

Ravi, let 'UserCounterMapper' extend 'IdentityMapper'. This way, you can set our special counters in UserCounterMapper's map api and then invoke IdentityMapper's map() api. Thoughts?
