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

Streaming scripts need more information
---------------------------------------

                 Key: HADOOP-4233
                 URL: https://issues.apache.org/jira/browse/HADOOP-4233
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/streaming
            Reporter: Andrey Gladyshev


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"));
