map.input.file returns null for MultipleInputs in Hadoop 0.20.2 version

[Sahana Bhat]

Hi,

          I found this link
https://issues.apache.org/jira/browse/MAPREDUCE-1743 related to the subject
of my mail.Has this been resolved as yet or is there any workaround to get
the filename while using MultipleInputs?

We have a restriction to use Hadoop 0.20.2 version as the 0.21.0 version
release (says unstable,unsupported).Also MultipleInputs uses JobConf and
hence i cannot get the context object to retrieve the filename :( .

Any help in this regard would be great!!

Thanks,
Sahana
