Description

Using file globbing to select various input paths, like so:

conf.setInputPath(new Path("mr/input/glob/2008/02/

{02,08}

"));

gives an exception:

Exception in thread "main" java.io.IOException: Illegal file pattern:

The code for JobConf.getInputPaths tokenizes using
a comma as the delimiter, producing two paths
"mr/input/glob/2008/02/

{02" and "08}

".
