[jira] Commented: (HADOOP-4233) Streaming scripts need more information

["Arun C Murthy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12633034#action_12633034 ] 

Arun C Murthy commented on HADOOP-4233:
---------------------------------------

I believe all parameters in JobConf are converted to env. variables already:

map.input.file == env['map_input_file']

In general dots are converted to underscores... could you please check?

> Streaming scripts are lack of useful information.
> For example we need job.get("map.input.file")) in script.
> Information can be provide by environment variable.
> It's easy to implement by adding in PipeMapRed.configure() something like:
> // add HADOOP_INPUTFILE environment variable with the value of input filename
> envPut(childEnv, "HADOOP_INPUTFILE", job_.get("map.input.file"));
