Thiruvalluvan M. G. updated AVRO-912:
-------------------------------------
Attachment: AVRO-912.patch
The attached patch addresses problems 1 and 2 by:
1. Using {{File}} instead of URL for passing executable filename.
2. Uses a {{List<String>}} instead of {{String}} to pass command arguments.
While serializing the commands arguments into {{JobConf}}, it uses {{\n}} as
delimiter.
The patch does not address the problem 3. Java 6's {{ProcessBuilder}} does not
have a mechanism to redirect output or error. ({{ProcessBuilder}} in Java 7 has
a platform independent solution, though). But the current thing using bash
works if the windows machine has {{cygwin}}.

> The problems are:
> 1. The executable filename is passed around as a URL. Windows filenames are
> valid URLs.
> 2. Typical windows user's home directory is {{c:\Documents and
> Settings\username}}. Maven puts the downloaded jar files under {{$HOME/.m2}}.
> So the classpath has several directories with space in their names. Splitting
> command line arguments using space generates invalid classpath.
> 3. Hadoop's {{TaskLog.captureOutAndError()}} generates command line for unix
> systems using bash.
