Subject [jira] Commented: (MAPREDUCE-1466) FileInputFormat should save #input-files in JobConf
Date Wed, 31 Mar 2010 14:28:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12851879#action_12851879

Amareshwari Sriramadasu commented on MAPREDUCE-1466:
----------------------------------------------------

I don't think the test in org.apache.hadoop.mapreduce.lib.input.TestFileInputFormat needs
to use Mockitto framework. Why don't we add a test similar to the one in old api?

> We already track the amount of data consumed by MR applications (MAP_INPUT_BYTES), alongwith,
it would be useful to #input-files from the client-side for analysis. Along the lines of MAPREDUCE-1403,
it would be easy to stick in the JobConf during job-submission.
