Amareshwari Sriramadasu updated MAPREDUCE-600:
----------------------------------------------
Issue Type: Improvement (was: Bug)
> Streaming command should be able to take its input from a "file", rather then
> from stdin
> ----------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-600
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-600
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/streaming
> Reporter: arkady borkovsky
>
> In some cases, especially when a streaming command is a 3rd party or legacy
> application,
> it is impossible of inconvenient to make it take its input from stdin.
> The command may require that the input file name is specified as a command
> line option, or the input file name is hard coded.
> The streaming infrastructure should allow to specify a name that can be used
> in open() to create an input stream equivalent to what would be fed to a
> streaming command as stdin by default.
