Subject [jira] [Commented] (MAPREDUCE-2493) New Api FileOutputFormat does not honour user specified OutputCommitter
Date Mon, 14 Nov 2011 14:26:51 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13149646#comment-13149646
] 

Bhallamudi Venkata Siva Kamesh commented on MAPREDUCE-2493:
-----------------------------------------------------------

When we use new API, the OutputCommitter associated with the FileOutputFormat is FileOutputCommitter.
Where as for the old API, OutputCommitter is reading from the conf object.

{code}
    if (useNewApi) {
      if (LOG.isDebugEnabled()) {
        LOG.debug("using new api for output committer");
      }
      outputFormat =
        ReflectionUtils.newInstance(taskContext.getOutputFormatClass(), job);
      committer = outputFormat.getOutputCommitter(taskContext);
    } else {
      committer = conf.getOutputCommitter();
    }
{code}

> o.a.h.mapreduce.lib.output.FileOutputFormat always uses the default FileOutputCommitter.
It ignores the user specified OutputCommitter.
