[jira] [Commented] (MAPREDUCE-1122) streaming with custom input format does not support the new API

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13842465#comment-13842465 ] 

Mathias Herberts commented on MAPREDUCE-1122:
---------------------------------------------

What is needed for this issue to move forward? Input and Output formats using the new API will become more and more frequent these days, people using streaming won't be able to benefit from those.

> When trying to implement a custom input format for use with streaming, I have found that streaming does not support the new API, org.apache.hadoop.mapreduce.InputFormat, but requires the old API, org.apache.hadoop.mapred.InputFormat.
