Subject [jira] Commented: (HADOOP-1010) getReordReader methof of InputFormat class should handle null reporter argument
Date Mon, 12 Feb 2007 22:01:10 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12472436

Milind Bhandarkar commented on HADOOP-1010:
-------------------------------------------

The way I see it, reporter is just another output stream coming out of the task. It should
get a uniform treatment just like other streams. Context is a good abstraction, since we would
be able to hang non-Strings (such as the task's stream-set) to it.

> In some cases, I need to create a record reader object in the config method of mappers.

> At that time, reporter is not available yet. And logically, the reporter should not be
a required for getRecordReader anyway.
