Streaming command should be able to take its input from a "file", rather then
from stdin
----------------------------------------------------------------------------------------
Key: HADOOP-2235
URL: https://issues.apache.org/jira/browse/HADOOP-2235
Project: Hadoop
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.
