[jira] [Resolved] (MAPREDUCE-600) Streaming command should be able
to take its input from a "file", rather then from stdin
[ https://issues.apache.org/jira/browse/MAPREDUCE-600?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Allen Wittenauer resolved MAPREDUCE-600.
----------------------------------------
Resolution: Won't Fix
I'm going to close this as won't fix. For applications that need a file, with the introduction of YARN, there are better ways to do this than run through the streaming interface.

> Key: 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.
