---------------------------------------------
Assignee: Christopher Zimmerman
> Make streaming to handle non-utf8 byte array
> --------------------------------------------
>
> Key: HADOOP-1722
> URL: https://issues.apache.org/jira/browse/HADOOP-1722
> Project: Hadoop
> Issue Type: Improvement
> Components: contrib/streaming
> Reporter: Runping Qi
> Assignee: Christopher Zimmerman
>
> Right now, the streaming framework expects the output sof the steam process
> (mapper or reducer) are line
> oriented UTF-8 text. This limit makes it impossible to use those programs
> whose outputs may be non-UTF-8
> (international encoding, or maybe even binary data). Streaming can overcome
> this limit by introducing a simple
> encoding protocol. For example, it can allow the mapper/reducer to hexencode
> its keys/values,
> the framework decodes them in the Java side.
> This way, as long as the mapper/reducer executables follow this encoding
> protocol,
> they can output arabitary bytearray and the streaming framework can handle
> them.
